Compiling and running
Compiling Hatari
- First, you need the SDL library, you can get it at:
-http://www.libsdl.org/. Most
-distributions already ship a suitable version.
-Make sure to install the appropriate header files as well often called
-"libsdl-dev" or the like.
-
- Second, you need the zLib compression library. You can get it from http://www.gzip.org/zlib/
-but the version shipped with your distribution will be sufficient in
-most cases. Make sure to have the header files
-for it installed as well.
-
-
-Of course, you need the GNU C compiler and (GNU) Make, too!
-
- Change to the hatari/ directory and adapt the configuration file
-Makefile.cnf to suite your system.
-Alternatively, you can use the supplied configure script to auto-detect
-all parameters (type " ./configure --help"
-to see the options of the script).
-Don't forget to use some good CFLAGS for the compiler optimizations, e.g.
-run configure in the following way:
-
+Required:
+
+
+Optional:
+
+- The PNG image library for PNG format screenshots and to
+decrease AVI video recording file sizes. You can get it from
+http://www.libpng.org/.
+- The GNU Readline library for Hatari debugger command line editing.
+- The Xlib library to support Hatari Python UI window embedding
+on systems with the X window system (Linux and other unixes).
+- The portaudio library for Falcon microphone recording support
+
- CFLAGS="-O3 -fomit-frame-pointer" ./configure
+The versions available in your Linux distribution will be sufficient
+in most cases, but make sure you have also the header files installed
+for the libraries as well! Typically they're in a corresponding -dev
+package.
+
+
+After you've verified that you have the required libraries and their
+development files, change to the hatari/
+directory. Create a build/ directory under
+it and configure the build system for your environment:
+
+mkdir -p build
+cd build
+cmake ..
+
Then compile Hatari by typing make.

+If all works fine, you'll get the executable hatari

+Note: Instead of calling CMake directly, you can also use the supplied

+prefix) in a format familiar from GNU Autotools using programs. Type
+"./configure --help"
+to see all the options supported by this script.

Installation of a TOS ROM
Before you can start Hatari, you have to copy a TOS ROM image to the data
-directory (the data directory is specified
-in the configuration file Makefile.cnf) and
+directory (<prefix>/share/hatari/, by
+default /usr/local/share/hatari/) and
rename it to tos.img, or use the
--tos command line option to tell
Hatari where to find a TOS ROM.

+ First you can select the CPU type here. Here are some important hints for
+ choosing the correct CPU type:
+
+
+ -
+ Atari ST and STE have only been shipped with a 68000 CPU, so for best
+ compatibility with old programs, choose this CPU type.
+
+ -
+ Atari TT and Falcon computers were using the 68030 CPU, so you should switch
+ use 68EC030+FPU (Hatari doesn't support 030 with MMU and some programs don't
+ work with 68020 so this is the best choice).
+
+ -
+ TOS 1.0x only works with 68000, while TOS 3.0x and 4.0x work only with a CPU
+ >= 68020.
+
+ -
+ 68010 and 68040 have never been used in official Atari computers, so don't
+ use these CPU types unless you've got some good reasons.
+
+
+
+
+ Beside the CPU type, you can also choose the machine type to emulate.
+ The ST was the very first 16/32-bit computer from Atari. Most older games
+ and demos require an ST. The STE was introduced some years later and had
+ some more advanced hardware features. There are not that many demos or
+ games that really require an STE but since most normal ST games/demos also
+ work with an STE, it's normally safe to always work in STE mode.
+
+ TT and Falcon are more advanced, but they are not as compatible to the ST as
+ the STE was. Therefore many old games and demos do not work with these machine
+ types anymore. There were only very few programs that were made for the TT
+ exclusively, while there were some interesting games and demos specially made
+ for the Falcon.
+ Note: TT and Falcon emulation are incomplete. They may not work
+ very well.
+
+
+ For STE emulation a STE compatible TOS image, e.q. version 1.06, 1.62 or
+ 2.x, is strongly recommended. For TT emulation you need TOS 3.0x and for Falcon
+ emulation you need TOS 4.0x. EmuTOS can be used on all machine types.
+
+
+ Select the CPU clock you want to use. 8Mhz is ST standard and the most
+ compatible. Use 16MHz for Mega STE and Falcon emulation.
+ The CPU in the TT was clocked with 32 MHz.
+
+With the "Slower but more compatible CPU" option, you can enable
the emulation of 68k address errors and the CPU prefetch buffer. This is needed
for best compatibility, but it slows down emulation a little bit so you can
disable it if you don't need it.
+
+ For Falcon mode, you can choose whether you want to enable DSP emulation,
+ fake it or completely disable it. Most Falcon programs only play sound or work
+ correctly when you enable the DSP emulation, but it needs a lot of host CPU
+ power (more than 2 GHz). So if you have a slow host CPU, you can try if your
+ Falcon program also runs with DSP disabled or in "dummy" mode.
+ Note that you can not change this option while the DSP based program already
+ runs.
+
You can also enable/disable Blitter emulation here. The Blitter is a custom
chip that accelerates some graphical operations. This switch only toggles the
Blitter in plain ST mode. In STE mode, the Blitter is always enabled (since all
STEs have been sold with a Blitter chip).

+
If you enable the "Real time clock emulation" switch, a RTC will
be emulated based on the time of the host computer. Note that you need at least
TOS 1.02 for proper RTC emulation, TOS 1.00 does not support this.
The Timer-D patch changes the Timer-D initialization from TOS. TOS uses
the MFP timer D as a baudrate generator for RS232. However, the TOS default
value slows down the emulation. The patch gives you a better performance.

does not work, you can try to disable the patch to see if it works then.

-NOTE: These parameters are very sensitive to the emulated
-ST and it is strongly recommended to

+Hard disk support
-ACSI hard disk emulation
-To use the ACSI hard disk emulation, you need a hard disk image file

-Please note that AHDI 5.0 is the only hard disk driver that

-
-
-To create a new ACSI hard disk image, you can start with an empty image that
-you have for example created with the following command:
-dd if=/dev/zero of=hd.img bs=512 count=xxx.
-Then copy the complete AHDI 5.0 package to a floppy disk image, and enable
-this floppy disk image and the fresh hard disk image in the emulator.
-Start HDX.PRG from the floppy disk and format and partition the hard disk
-with this tool. When you're finished, you have to restart the emulated system,
-run AHDI.PRG from the floppy disk and HINSTALL.PRG afterwards.
-With HINSTALL.PRG you can install the hard disk driver to the fresh HD image,
-so you can directly boot from the hard disk image in the future.
+Hatari supports three ways of emulating Atari hard drives: The low-level
+ACSI and IDE hard disk emulation and a GEMDOS based drive emulation.
+In most cases the GEMDOS based hard disk emulation is best as it allows
+exchanging files easily between the emulated and the host environment.
+
+
+Please note that changing the HD-image or the GEMDOS HD-folder will reset
+the emulated Atari since it is not possible to switch the hard disk
+while the emulator is running.
+
+
+On a 32-bit host system, the size of a hard disk image is limited to 2 GB.
+On 64-bit host systems, bigger images might be possible but the support
+for bigger images is not tested very well yet. How large partition sizes
+are supported inside the hard disk (images) depends on the TOS version.
+TOS 1.0x supports up to 256MB partitions and TOS 4.0x up to 1GB ones.

+
+With the GEMDOS based drive emulation, you can easily "mount" a
folder from the host file system to a drive of the emulated Atari. To
use the GEMDOS based drive emulation, you should use a folder on your
hard disk that only contains files and folders with valid TOS
-filenames.
-That means that all files/folders should be written in capital letters
-and their length mustn't exceed the 8+3 file name length limit. If you
-don't want to rename all files to get capital letters, it is also
-possible to store that folder on a FAT filesystem since those
-filesystems are case-insensitive.
-GEMDOS drive emulation is an easy way to share files between the
-host system and the emulated Atari, but it is known to be incomplete
-and
-a little bit unstable, especially if you use it together with the ACSI
-hard disk emulation. So if your programs complain that they could not
-find/read/write files on the GEMDOS HD drive, you should try to copy
-them to a floppy disk image or a real hard disk image!

+length limit.
+
+
+If you provide --harddisk option
+a directory containing only single letter (C-Z) subdirectories, each
+of these subdirectories will be treated as a separate partition,
+otherwise the given directory itself will be assigned to drive "C:".
+In the multiple partition case, the letters used as the subdirectory
+names will determine to which drives/partitions they're assigned.
+
+
+GEMDOS drive emulation is an easy way to share files between the
+host system and the emulated Atari, but there are also some known
+limitations which are due to the way the GEMDOS drive emulation is
+implemented:
+
+
+- It is not possible to use a cartridge image at the same time
+with the GEMDOS drive emulation (Hatari has it's own cartridge code
+that is used for GEMDOS emulation).
+- As MiNT installs its own GEMDOS handler, it doesn't work with
+the GEMDOS drive emulation. MiNT needs to be booted from a real hard
+disk image.
+- GEMDOS drive emulation conflicts with the ACSI and IDE harddisk images.
+If you want to use GEMDOS HD emulation and ACSI/IDE disk images together,
+use a multiple partition GEMDOS emulation setup and select the partition
+subdirectories (letters) so that they don't conflict with the ACSI/IDE
+drive partitions (letters). With HD Driver you have also another option,
+see Using HD Driver
+with GEMDOS partitions.
+- The GEMDOS drive emulation does not work (very well) with TOS
+1.00 and 1.02. Use at least TOS 1.04 if you want the GEMDOS drive
+emulation to work properly.
+
+
+So, if your programs complain that they could not find/read/write
+files on the GEMDOS emulated drive, you should try to copy them to a
+floppy disk image or a real hard disk image!
+
+
+ACSI hard disk emulation
+
+To use the ACSI hard disk emulation, you need a hard disk image file
+with a pre-installed HD driver in it. You can try to get an image of
+your old ST hard disk or grab one from the internet (e.g. from the
+Hatari website).
+
+
+To create a new ACSI hard disk image, you can start with an empty
+image that you have created for example with the following command:
+dd if=/dev/zero of=hd.img bs=512 count=xxx
+(where 'xxx' is size in 512 byte blocks). Copy the complete AHDI 5.0
+package to a floppy disk image, then boot Hatari with this floppy disk
+image and the fresh hard disk image like this:
+--acsi hd.img ahdi.st.
+Then start HDX.PRG from the floppy disk and format + partition the hard
+disk image with it.
+
+
+Formatting and partitioning works currently only with AHDI 5, but you
+can install the AHDI 6 driver to the hard disk after it's formatted.
+Restart the emulated system, run AHDI.PRG from the floppy disk to access
+the hard disk image from the emulated Atari and then run HINSTALL.PRG.
+After installing the hard disk driver to the fresh HD image with
+HINSTALL.PRG, you can boot directly from the hard disk image.
+
+
+IDE hard disk emulation
+
+
+As the IDE disk format (little endian) differs from the ACSI disk format
+(big endian), you need separate disk images for them. Hatari doesn't
+currently support formatting IDE disks with AHDI, but you can do it with
+Cecile.
+
+
+First create an empty image file with the size of your choice with:
+dd if=/dev/zero of=hd.img bs=1k count=xxx.
+Then get the Cecile hard disk driver from
+http://centek.free.fr/atari/softs/s_cecile.htm
+and put it on a floppy disk image (e.g. to one named "cecile.st" using:
+zip2st.sh cecile.zip).
+
+
+Run Hatari with
+hatari --machine falcon --tos tos404.rom
+--ide-master hd.img cecile.st, switch to larger color resolution
+and warm up your French language skills. Then start the Cecile hard
+disk driver CECILE.PRG and run CC_TOOLS.APP to partition your hard
+disk image. Click the "Partition" button, select "Hatari IDE disk" and set
+suitable partition size with the arrows (below type field). Then click
+"Valider".
+
+
+If you only want to use your HD image in Falcon mode, you can install
+the Cecile hard disk driver to the image from the Cecile CC_TOOLS.APP:
+Click the "Installer" button and save the Cecile driver to the
+1st partition on "Hatari IDE disk". If you want to also use your HD
+image in ST/STE mode, you need to get and install AHDI 6 driver on it
+instead (see ASCI hard disk
+emulation section).
+
+
+Then you can boot from your hard disk image by simply specifying it
+with the --ide-master parameter.
+
+
+
+Moving files
+to/from hard disk images
+
+Moving files to and from Atari hard disk images can be done
+either through GEMDOS partitions (host directories mounted inside
+Hatari emulation) or accessing the images directly on the host
+(outside the emulation). Both have their own limitations.
+
+If it's fine for the IDE/ACSI partitions to be first, you can use
+hard disk images with AHDI or Cecile driver and a multipartition
+GEMDOS setup as described in above sections. If you want to boot from
+a GEMDOS partition i.e. such to be before hard disk image partitions,
+and still to be able to access all the IDE/ACSI partitions, you need to
+use HD Driver.
+
+Using HD Driver
+with GEMDOS partitions
+
+Uwe Seimet's HD
+Driver works fine with both the Hatari GEMDOS partitions and normal
+hard disk images. However, it doesn't work with EmuTOS so you need
+real TOS (at least version v1.04).
+
+
+First copy the HDDRIVER.PRG binary into your GEMDOS drive emulation
+directory AUTO folder. Then start the HDDRUTIL.APP configuration utility,
+locate HDDRIVER.PRG, open the
+"Devices
+and Partitions" dialog and select the "Preserve Existing Partitions"
+option. Then you can just start Hatari with your hard disk image and
+this GEMDOS directory, for example like this:
+"hatari --harddisk gemdos-hd/ --ide-master
+ide-hd.image".
+
+If you're using the demo version of HD Driver, you can
+write files only to the C: partition, i.e. in above case only copy
+files from the hard disk image partition to the GEMDOS partition (with
+some write slowndowns included into the demo version). If you want to
+copy files to the hard disk image with the demo version of
+the HD Driver, you need to set the hard disk image as drive C:.
+
+To accomplish this, set the GEMDOS partitions to be from D: forward,
+i.e. have a directory which contains only single letter subdirectories,
+starting from "D" like in "mkdir gemdos-hd;
+mkdir gemdos-hd/D". Then give Hatari (as the last parameter)
+a boot floppy image containing the demo version of HDDRIVER.PRG in
+its AUTO folder, like this: "hatari
+--ide-master ide-hd.image --harddisk gemdos-hd/ hd-driver-floppy.st".
+
+
+
+Accessing
+HDD image partitions outside of Hatari
+
+
+If you want to access the harddisk image partitions also outside
+the emulation, the disk image needs to have a DOS partition table.
+The atari-hd-image script included
+with Hatari can be used to create such an image.
+
+
+Inside the Hatari emulator, EmuTOS can access partition(s) on these
+kind of images directly without any driver software. Of the Atari HD
+drivers mentioned above, Centek's Cecile and Uwe Seimet's HD Driver
+(demo) work fine with these partitions. E.g. AHDI and CBHD don't.
+
+
+Note that plain EmuTOS supports only ACSI and the listed HD drivers
+support only IDE (emulation). Cecile needs TT or Falcon and HD Driver
+doesn't work with EmuTOS. To summarise; if ASCI emulation and
+EmuTOS are enough, use those. Otherwise, if you want to use TT or
+Falcon emulation, use Cecile (or full HD Driver version if you have
+it), otherwise use HD Driver (demo).
+
+
+To access the content of the partitions on Linux host, there are two
+possibilities:
+
+
Using Mtools
+
+For this you need to add an entry for the hard disk
+image to your ~/.mtoolsrc and
+specify which partition you want to access from the image. For
+an image created with the above mentioned script, the line in
+the configuration file should look something like this:
+
+
+MTOOLS_NO_VFAT=1
+drive c: file="/home/user/hatari/hd.img" partition=1
+
+
+Note that Mtools is instructed to use FAT compatibility mode because
+EmuTOS cannot deal properly with VFAT file information. If you don't
+want this setting for all your Mtools drives, you can set it also via
+the environment like this ("::" refers to the drive image given with
+the "-i" option):
+
+
+MTOOLS_NO_VFAT=1 mcopy -spmv -i hd.img files/* ::
+
+
+Using a loopback device
+
+This is recommended even by Mtools documentation, but it's less
+convenient as it requires root rights. First you need to "loop"
+mount the image:
+
+
+$ su
+# image="hd.img"; mountdir="hd"
+# start=$(parted $image unit s print | awk '/ 1 /{print $2}' | tr -d s)
+# losetup -f $image -o $((512*$start))
+# loop=$(losetup -a | tail -1 | cut -d: -f1)
+# mkdir -p $mountdir
+# mount -t msdos $loop $mountdir
+
+
+This uses parted to find out the first
+partition offset in sectors and then tells losetup
+to bind the first free loop device to a corresponding offset from
+the hd.img image.
+mount is then used to mount the file system
+from the loop device on top of the "hd" directory.
+
+
+After you've copied the relevant files to the "hd" directory, you need
+unmount the file system and remove the loop device binding before using
+the disk image from Hatari:
+
+
+# umount $mountdir
+# losetup -d $loop
+
+
+The debugger
+
+
+Hatari has a built-in debugging interface which can be used for
+analyzing code that runs in the emulated system. To invoke the
+debugger, press the AltGr + Pause
+key combination.
+
+
+
+If you start Hatari with the "-D" command line option, m68k
+exceptions will automatically invoke the debugger. You can
+toggle this also later from the debugger with the "setopt -D"
+command.
+
+
+
+To run debugger commands at Hatari startup, one can use the "--parse
+<file>" command line option. This is useful e.g. for debugging
+TOS or some demo startup code, or if you always want to use some
+specific debugger setup (breakpoints etc).
+
+
+
+The debugger uses Hatari's parent console window, so make sure you run
+Hatari from the command line when you want to use the debugger. On
+Linux you can add for example an icon to your desktop that does it
+with something like this (replace "xterm" with your favorite terminal
+program):
+
+
+xterm -T "Hatari debug window" -e hatari

+
+Entering arguments to debugger commands
+
+
+After writing (with TAB completion) one of the above command names,
+pressing TAB will (for most commands) show all the available subcommands.
+
+
+
+If you want to give numbers in other number bases
+than the default/selected one, they need to be prefixed with a
+character indicating this. For decimals this prefix is "#" (#15),
+for hexadecimals "$" ($F), and for binary values it's "%" (%1111).
+
+
+
+By default debugger expects all numbers without a prefix to be
+decimals, but you can change the default number base with the "setopt"
+command, just give it the desired default number base (bin/dec/hex).
+When using the hexadecimal number base, remember still to prefix
+hexadecimal numbers with '$' if they could be confused with register
+names (a0-7, d0-7)! Otherwise results from expressions and
+conditional breakpoints can be unexpected.
+
+
+
+Calculations and immediate evaluation
+
+
+Instead of a number, you can also use an arithmetic expression, by
+surrounding it with quotes (""). An expression can contain
+calculations with CPU and DSP register, symbol and Hatari variable
+values in addition to numbers. For example to give a sum of A0 and
+D0 register values to a command, use "a0+d0".
+
+
+
+Within arithmetic expressions parenthesis are used both to change
+the order of precendence and to indicate indirect addressing.
+Unlike with conditional breakpoint expressions (explained below), you
+cannot give size for the indirect addressing, a long value is always
+read from the RAM address given within parenthesis. For example to
+get a long value pointed by stack pointer + 2, use "(a7+2)".
+
+
+
+Values of arithmetic expressions are always evaluated before being
+given to a command. Except for "evaluate" and "address" commands,
+they always need to be marked with quotes (""). Besides arithmetics,
+this can be used also to give symbol/register/variable values to
+commands that don't otherwise interpret them. If command complains
+that it didn't recognize e.g. a register name, just put it to quotes
+and it will be "evaluated" before being given to the command.
+
+
+
+With command argument completion (see build
+notes), result from the last "evaluate" command can be inserted
+by typing '$' and pressing TAB.
+
+
+
+Inspecting emulation state
+
+
+In the beginning, probably the most interesting commands are "m" and "d"
+for dumping and disassembling memory regions. You can use "dm" and "dd"
+commands to do the same for the DSP.
+
+
+> help memdump
+'memdump' or 'm' - dump memory
+Usage: m [start address-[end address]]
+ dump memory at address or continue dump from previous address.
+
+
+> help disasm
+'disasm' or 'd' - disassemble from PC, or given address
+Usage: d [start address-[end address]]
+ If no address is given, this command disassembles from the last
+ position or from current PC if no last position is available.
+
+
+> disasm pc
+$00aa6e : 2f08 move.l a0,-(sp)
+$00aa70 : 0241 0fff andi.w #$fff,d1
+$00aa74 : 207c 00fe 78c0 movea.l #$fe78c0,a0
+$00aa7a : 2070 1000 movea.l (a0,d1.w),a0
+$00aa7e : 4ed0 jmp (a0)
+
+
+
+Both commands accept in addition to numeric addresses also register
+and symbol names, like in above example. If you don't specify an
+address, the commands continue showing from an address that comes
+after the previously shown data. "disasm" command default address
+will be reseted to PC address everytime you re-enter the debugger.
+
+
+
+You can use the "info" command to see state of specific sets of HW
+registers (e.g. "info videl") and Atari OS structures (e.g. "info gemdos").
+
+
+
+Selecting what information is shown on entering the debugger
+
+
+By using the "lock" command, you can ask Hatari to show specific
+information whenever you enter the debugger / hit a breakpoint. For
+example to see disassembly from current PC address, use "lock disasm".
+
+
+
+With the "regaddr" subcommand, you see disassembly or memory
+dump of an address pointed by a given register ("lock regaddr disasm
+a0"). Of the DSP registers, only Rx ones are valid for this
+subcommand.
+
+
+
+"file" subcommand can be used to get (arbitrary number of) commands
+parsed and executed from a given debugger input file whenever debugger
+is entered. With this you can output any information you need:
+
+
+lock file debugger.ini
+
+
+
+To disable showing of this extra information, use "lock default".
+Without arguments "lock" command will show the available options
+(like the "info" command does).
+
+
+
+Debug symbols
+
+
+You can load symbol name/address information from a file to the
+debugger with the "symbols" command (and with "dspsymbols" for DSP).
+These symbolic names can be used in arithmetic expressions and
+conditional breakpoint expressions. They also show up in the "disasm"
+command output.
+
+
+The symbols file format is following:
+
+e01034 T random
+e01076 T kbdvbase
+e0107e T supexec
+
+
+Where 'T' means text (code), 'D' means data and 'B' means BSS section
+type of address. The hexadecimal address, address type letter and the
+symbol name are separated by white space. Empty lines and lines
+starting with '#' (comments) are ignored.
+
+
+
+AHCC C-compiler can provide a symbol file suitable for this with its
+"-n" 'nm' list option (not enabled by default). If you're reverse
+engineering some code, you could just create your own symbols file to
+help in debugging it later.
+
+
+
+If you're debugging normal TOS/GEM programs instead of code loaded
+into a fixed address (like e.g. EmuTOS is), after the program has been
+loaded, load the symbols with the program text segment address offset:
+
+
+symbols calc.sym "TEXT"
+
+
+(The value of the above virtual "TEXT" debugger variable comes from a
+program basepage, it's set after the program is loaded by TOS, see
+"info basepage" output.)
+
+
+
+Breakpoints
+
+
+There are two ways to specify breakpoints for Hatari. First, there are
+the simple address breakpoints which trigger when the CPU (or DSP)
+program counter hits a given address. Use "a" (or "da" for the DSP)
+to create them, for example:
+
+
+a $e01034
+a some_symbol
+
+
+
+Note that address breakpoints are just wrappers for conditional
+breakpoints so you need to use "b" command to remove or list them.
+
+
+
+Then there are the conditional breakpoints which can handle much more
+complex break condition expressions; they can track changes to
+register and memory values with bitmasks, include multiple conditions
+for triggering a breakpoint and so on. Use "b" (or "db" for the DSP)
+to manage them.
+
+
+Help explains the general syntax:
+
+> help b
+'breakpoint' or 'b' - set/remove/list conditional CPU breakpoints
+Usage: b <condition> [&& <condition> ...] [:<option>] | <index> | help | all
+
+Set breakpoint with given <conditions>, remove breakpoint with
+given <index>, remove all breakpoints with 'all' or output
+breakpoint condition syntax with 'help'. Without arguments,
+lists currently active breakpoints.
+
+
+
+Unless you give breakpoint one of the pre-defined subcommands ('all',
+'help'), index for a breakpoint to remove or no arguments (to list
+breakpoints), the arguments are interpreted as a new breakpoint
+definition.
+
+
+
+Each conditional breakpoint can have (currently up to 4) conditions
+which are separated by "&&". All of the breakpoint's
+conditions need to be true for a breakpoint to trigger.
+
+
+
+Breakpoint options
+
+
+Normally when a breakpoint is triggered, emulation is stopped and you
+get to the debugger. Breakpoint options can be used to affect what
+happens when a breakpoint is triggered. These options are given after
+the conditions and are prefixed with ':'.
+
+
+
+- <count>
+- Break only on every <count> hit. For example, to stop
+on every other time PC is at given address, use:
+
+a $1234 :2
+
+
+
+- once
+-
+Delete the breakpoint when it's hit i.e. trigger it only once. It may
+be useful if you just want to get a specific address. Or if you're on
+an instruction that jumps back to a start of the loop and you want to
+finish the loop, you couuld use:
+
+b pc > "pc" :once
+continue
+
+
+
+- trace
+-
+Continue emulation without stopping after printing the value that
+triggered the breakpoint and doing other possible option actions.
+This is most useful when investigating memory or register value
+changes (explained below).
+
+
+- lock
+-
+Show the same information on breakpoint hit as you see when entering
+the debugger (see the "lock" command in
+Inspecting emulation state
+above). This enables also trace option as you would anyway see this
+information if debugger would be entered.
+
+
+- file <file>
+-
+Execute debugger commands from given <file> when this breakpoint
+is hit. With this you have complete control over what information is
+show when the debugger is hit, you can even chain breakpoints (as
+explained in
+Chaining breakpoints later on)
+etc. Use this if "lock" option isn't enough or you want different
+information show on breakpoints and when entering the debugger.
+
+
+
+
+Note: you can give multiple options for conditional breakpoints, but
+for address breakpoints you can give only one these options. And
+"file" option is supported only for conditional breakpoints.
+
+
+
+Breakpoint conditions
+
+
+"b help" explains very briefly the breakpoint condition syntax:
+
+
+> b help
+condition = <value>[.mode] [& <mask>] <comparison> <value>[.mode]
+
+where:
+ value = [(] <register/symbol/variable name | number> [)]
+ number/mask = [#|$|%]<digits>
+ comparison = '<' | '>' | '=' | '!'
+ addressing mode (width) = 'b' | 'w' | 'l'
+ addressing mode (space) = 'p' | 'x' | 'y'
+
+
+
+For CPU breakpoints, mode is the address width; it can be byte ("b"),
+word ("w") or long ("l", default). For DSP breakpoints, mode specifies
+the address space: "P", "X" or "Y". Note that on DSP only R0-R7
+registers can be used for memory addressing. For example;
+
+db (r0).x = 1 && (r0).y = 2
+
+
+
+If the value is in parenthesis like in '($ff820)' or '(a0)', then the
+used value will be read from the memory address pointed by it. Note
+that this conditional breakpoint expression value is checked at
+run-time whereas quoted arithmetic expressions (mentioned in
+Entering arguments
+to debugger commands above) are evaluated already when
+adding a breakpoint. For example, to break when a value in an address
+(later) pointed by A0 matches the value currently in D0, one
+would use:
+
+
+b (a0) = "d0"
+
+
+
+If you're interested only on certain bits in the value, you can use
+'&' and a numeric mask on either side of comparison operator to
+mask the coresponding value, like this:
+
+b ($ff820).w & 3 = (a0) && (a1) = d0 & %1100
+
+
+
+Comparison operators should be familiar and obvious, except for '!'
+which indicates inequality ("is not") comparison. For example:
+
+
+b d0 > $20 && d0 < $40 && d0 ! $30
+
+
+
+As a convenience, if the both sides of the comparison are exactly the
+same (i.e. condition is redundant as it's always either true or
+false), the right side of the comparison is replaced with
+its current value. This way you can give something like this:
+
+
+b pc > "pc"
+
+As:
+
+b pc > pc
+
+
+
+That in itself isn't so useful, but for inequality ('!') comparison,
+conditional breakpoint will additionally track and output all further
+changes for the given address/register expression. This can be used
+for example to find out all value changes in a given memory address,
+like this:
+
+
+b ($ffff9202).w ! ($ffff9202).w :trace
+
+
+Typically with this one would use the breakpoint "trace" option like
+above.
+
+
+
+Breakpoint variables
+
+
+In addition to loaded symbols, the debugger supports also setting
+conditional breakpoints on values of some "virtual" variables listed
+by "b help". For example:
+
+
+
+
+Hint: "info" command "aes", "gemdos" and "vdi" subcommands for can be
+used to list the corresponding OS-call opcodes. For example,
+to see the GEMDOS opcodes, use:
+
+info gemdos 1
+
+
+
+
+Chaining breakpoints and other actions
+
+
+As the file pointed by the breakpoint ":file" option (see
+Breakpoint options) can contain any
+debugger commands, it can also be used to do automatic "chaining" of
+debugger and breakpoint actions so that after one breakpoint is hit,
+another one is set.
+
+
+For example if you have these input files:
+
+- "break.ini":
+
+b GemdosOpcode = 0x3D :trace :file trace.ini
+
+
+- "trace.ini":
+
+setopt --bios-intercept --trace gemdos,xbios,fdc,io_all
+b VBL = "VBL+4" :trace :file disable.ini
+
+
+- "disable.ini":
+
+trace none
+b all
+
+
+
+
+
+And then start Hatari with the first debugger input file and a GEMDOS
+harddisk directory containing "desktop.inf" file:
+
+
+hatari --parse break.ini -d testdir
+
+
+
+- "break.ini" input file will break when TOS opens
+ the "desktop.inf" file (it's the first Fopen() i.e. GEMDOS call
+ 0x3D done by TOS at boot) and the breakpoint will run
+ the debugger commands from the "trace.ini" file
+
- "trace.ini" input file sets Hatari to trace several things
+ (see Tracing section below) in the
+ emulated system for few VBLs until breakpoint runs commands
+ from the "disable.ini" file
+
- "disable.ini" input file will disable tracing and remove
+ all (remaining) breakpoints
+
+
+
+Note: because debugger input files cannot "continue"
+emulation, ":trace" option needs to be used for the breakpoint(s)
+if you want emulation to continue after the breakpoint action(s).
+
+
+
+Hint: It's better to test each input file separate before testing the
+whole chain. Besides the ":file" breakpoint option, these debugger
+input files can be also read with the debugger "file" command, "lock"
+command "file" option and with the Hatari "--parse" command line
+option.
+
+
+
+Tracing
+
+
+After analyzing the emulation state and/or setting new breakpoints,
+you can continue the emulation with the "c" command. You can continue
+for a given number of CPU instructions (or DSP instructions when "dc"
+is used), or you can continue forever (until a non-tracing breakpoint
+triggers) if you omit the instruction count.
+
+
+
+If you want to continue with real-time disassembling, you can enable
+it with "trace cpu_disasm" (or "trace dsp_disasm" for DSP) at the
+debugger prompt before continuing.
+
+
+Disable tracing with "trace none" when you enter the debugger again.
+"trace help" (or TAB) can be used to list all the (over 30) supported
+traceable things, from HW events to OS functions.
+
+
+Because Hatari normally emulates things at the hardware level, tracing
+certain Atari OS Traps requires setting additional Hatari options
+which tell it to intercept this higher level functionality:
+
+- BIOS and XBIOS tracing require enabling of the BIOS intercepting with
+ the "--bios-intercept" option (which has also some other side-effects)
+
+- GEMDOS tracing requires enabling the GEMDOS harddisk emulation
+ (which doesn't work under MiNT because it re-implements GEMDOS)
+
+
+If use of above isn't possible for the things you'd like to track,
+you can use the OS call opcode breakpoints explained above with the
+":trace" breakpoint option.
+
+
+Tracing options can be set even from a program within the emulation
+if you enable the Hatari "--bios-intercept" option and call XBios 255
+from the program with a suitable Hatari command line string. Bios
+interception will also show the (Bios level) CON: output on the host
+console.
+
+
+Note that the trace output file can be set only when Hatari starts,
+it cannot be changed from within the debugger (or emulation).
+
+
+
+Profiling
+
+
+Profiling tells where the emulated code spends most of its (emulated)
+time. It can be used to find out where a program is (apparently)
+stuck or what are the largest performance bottlenecks for a program.
+
+
+
+Profiling is used by first enabling the profiler (use "dp" for DSP):
+
+
+> profile on
+Profiling enabled.
+
+
+And profiling will start once you continue the emulation:
+
+
+> c
+Returning to emulation...
+Allocated CPU profile buffer (18 MB).
+
+
+
+When you get back to the debugger, the collected profiling information
+is processed and a summary of in which parts of the RAM the execution
+happened is shown:
+
+
+Allocated CPU profile address buffer (4 KB).
+Normal RAM (0-0x400000):
+- no activity
+Cartridge ROM (0xFA0000-0xFC0000):
+- no activity
+ROM TOS (0xE00000-0xE80000):
+- active address range:
+ 0xe0014c-0xe23f02
+- active instruction addresses:
+ 707 (100.00% of all)
+- executed instructions:
+ 629144 (100.00% of all)
+- used cycles:
+ 9408503 (100.00% of all)
+- address with most cycles:
+ 0xe0dcca, 402628 cycles (4.28% of all in area)
+- address with most hits:
+ 0xe004a4, 4900 hits (0.78% of all in area)
+
+
+(DSP RAM will be shown only as single area in profile information.)
+
+
+
+After this you can request more detailed profiling information:
+
+
+> profile
+'profile' - profile CPU code
+Usage: profile <on|off|counts|cycles|symbols|stats> [show count]
+ on & off enable and disable profiling. Data is collected
+ until debugger is entered again after which you can view
+ statistics about the data or view PC addresses that took
+ most cycles or functions/symbols called most often.
+ You can specify how many items are shown at most.
+
+
+For example:
+
+> profile counts 8
+addr: count:
+0xe004a4 0.78% 4900
+0xe004b6 0.78% 4896
+0xe0dcbc 0.55% 3448
+0xe0dcc6 0.55% 3448
+0xe0f59e 0.55% 3446
+0xe0dcce 0.55% 3445
+0xe0dcd6 0.55% 3445
+8 CPU addresses listed.
+
+
+If you have loaded symbol information for code addresses, with the
+"profile symbols" command you get a list of how many times the code
+execution passed through the defined symbol addresses.
+
+
+
+After the profiling information has been post-processed, it will
+also be shown in the disassembly output.
+
+
+
+Usage examples
+
+
+Here's a list of some common debugging tasks and how to do them
+with the Hatari debugger:
+
+
+
+- Stopping on program startup and examining its data
+- Please see Breakpoint variables
+and Inspecting emulation state
+sections.
+
+
+- Tracing specific things in the system
+- To trace e.g. all GEMDOS calls and IO operations, use:
+
+trace gemdos,io_all
+
+Please see Tracing section for more information
+on tracing, what's possible with it and what are its limitations.
+
+
+- Stopping when certain PC address is passed Nth time
+- To stop e.g. after function/subroutine at $12345 is called for
+the 6th time:
+
+a $12345 :6
+
+
+
+- Stopping when register has a specific value
+- To stop when e.g. D1 register contains value 5, set a breakpoint on:
+
+b d1 = 5
+
+
+
+- Stopping when a register value changes
+- To stop when e.g. D1 register value changes, set a breakpoint on:
+
+b d1 ! d1
+
+
+
+- Stopping when register value is within some range
+- To stop when e.g. D1 register value is within range of 10-30,
+set a breakpoint on:
+
+b d1 > 9 && d1 < 31
+
+
+
+- Stopping when memory location has a specific value
+- To stop when e.g. bit 1 of the Video Shifter Sync Mode byte at
+IO address $ff820a is set i.e. video frequency is 60Hz, set
+a breakpoint on:
+
+b ($ff820a).b & 2 = 2
+
+
+
+- Stopping when a memory value changes
+- To stop when above bit changes, set a breakpoint on its value
+being different from the current value ('!' compares for inequality):
+
+b ($ff820a).b & 2 ! ($ff820a).b & 2
+
+
+
+- Tracing all changes in specific memory location
+- To see the new values and continue without stopping, use
+the ":trace" breakpoint option:
+
+b ($ff820a).b & 2 ! ($ff820a).b & 2 :trace
+
+
+
+- Stopping at specific screen position
+- To stop e.g. when VBL is 100, HBL is 40 and line cycles is 5,
+use the corresponding debugger variables:
+
+b VBL = 100 && HBL = 40 && FrameCycles = 5
+
+
+
+- Stopping after value increases/decreases by certain amount
+- To stop e.g. after D0 value has increased by 10, set breakpoint on:
+
+b d0 = "d0 + 10"
+
+
+
+- Seeing code leading to a breakpoint
+- To see the instructions executed before debugger was entered,
+you need to enabled history tracking beforehand and then whenever the
+debugger is entered, you can request given number (here 16) of past
+instructions to be shown:
+
+history on
+c
+[breakpoint is hit and debugger entered]
+history 16
+
+
+
+- Getting instruction execution history for every breakpoint
+-
+To see last 16 instructions whenever (a normal or tracing) breakpoint
+is hit:
+
+history on
+lock history 16
+c
+
+
+
+- Single step so that new register values are shown after each step
+-
+
+lock registers
+c 1
+[new register values]
+c 1
+[new register values]
+...
+
+
+
+- Showing current stack contents
+- To see first 64 bytes on top of the stack, use:
+
+m "a7-64"-a7
+
+
+
+- Seeing specific information each time debugger is entered
+- To see above information whenever some breakpoint is hit,
+you enter debugger manually etc, write that command to e.g.
+stack.ini file and then use:
+
+lock file stack.ini
+
+Please see also Chaining breakpoints
+section for more examples on what you can do with the debugger input files.
+
+
+- Finding where program or OS is stuck
+- Profiling tells from which addresses CPU is running
+executing the instructions:
+
+profile on
+c
+[after a while, use AltGr+Pause to get back to debugger]
+profile counts
+
+
+
+
+
+
+Hint: for most of above commands, one just needs to prefix them with
+"d" (or "dsp" if using full command names) to do similar operation on
+DSP.
+
+
+
+Build notes
+
+
+Lastly, the debugger is much nicer to use with the command line
+history, editing and especially with the command, command argument and
+symbol name completion support. If you're building Hatari yourself,
+please make sure that you have the GNU readline development files
+installed (on Debian / Ubuntu these come from the libreadline5-dev
+package). Otherwise completion doesn't get enabled when you configure
+Hatari.
+
+
+
+ENABLE_TRACING define needs to be set for tracing to work.
+By default it should be enabled.
+
+
+
+Performance
+
+Hatari performance varies between Atari programs, depending on what
+features Hatari needs to emulate for them. Less accurate Atari
+emulators may be faster as emulation accuracy has a performance
+overhead.
+The operating system and libraries below Hatari can also sometimes
+have a noticeable effect on performance.
+
+
+Improving Hatari performance
+
+
+Hatari currently runs best in 16 or 32 bits per pixel color depth
+mode, so try to avoid 24 bits per pixel display modes if possible.
+16-bit mode is fastest.
+
+
+
+On OSX, frame skipping, zooming and drive LED options (listed below)
+seem to have a large effect on performance in the windowed mode.
+This is apparently due to issues in the SDL OSX backend and how OSX
+itself composites non-fullscreen window contents. OSX uses always
+32-bit mode.
+
+
+
+Unless you've disabled compiler optimizations (like GCC's -O2 or -O3
+options) in the Hatari build, the extra optimization flags (like GCC's
+"-mtune=i686") don't seem to have very large effect on Hatari
+performance. Using GCC -O3 option instead of -O2 can give minor
+(5-10%) performance improvements for things (demos) that use very
+heavily interrupts.
+
+
+
+However, Hatari can be sped up considerably by giving up some
+emulation or emulator accuracy. Except for DSP, these options
+should be needed only on very slow devices like handhelds. See below.
+
+
+
+If nothing else helps, try an earlier Hatari version. More accurate
+emulation or emulator output in newer Hatari versions means that they
+can be slower despite optimizations.
+
+
+
+Emulation options
+
+
+Emulation options have the largest impact on performance.
+These options can be changed from the Hatari GUI System dialog and
+the emulation needs to be rebooted for any of these changes to take
+an effect!
+
+
+DSP
+
+Emulating the Falcon DSP is performance-wise several times more demanding
+than emulating the m68k; DSP runs at higher frequency, executes many
+instructions for each m68k instruction and emulation isn't as mature
+and optimized. Unless some program needs DSP, none or
+dummy DSP emulation mode could be used. Even of the programs
+that do use DSP, many use it only for background music and work
+fine without the real DSP emulation.
+
+
+Timer-D
+
+The single largest factor contributing to general Hatari emulation
+performance is the handling of interrupts. Enabling Timer-D patching
+option (about) doubles Hatari ST/STE emulation performance as it
+significantly reduces the number of interrupts generated by the emulated
+Atari machine. Using this has adverse effect only for very rare programs.
+
+
+Compatible CPU
+
+After the DSP and interrupts, m68k emulation takes most time.
+Disabling the "Slower but more compatible CPU" option will speed up
+the emulation a lot, but it won't anymore be cycle accurate. This can
+be fine for many games and other programs, but won't work e.g. for demos
+using overscan or rasters.
+
+
+
+Roughly speaking, for DSP emulation, one needs at least 2Ghz machine.
+For normal (unpatched) Timer-D frequency on some specific cases (like
+demos with overscan 512 color animations) one may need over 1GHz
+machine, but some rare ST/STE demos may require over 1GHz machine even
+with Timer-D patching. For "Compatible CPU" one needs at least 1/2Ghz
+machine.
+
+
+
+NOTE: Above options may cause some programs not to work correctly.
+The Hatari Software Compatibility List
+lists programs known to need real real Falcon DSP emulation or Timer-D
+frequency. Disabling "Compatible CPU" option is recommended only as
+a last resort.
+
+
+
+Emulator options
+
+
+Emulator options don't usually have as large effect on performance as
+emulation options, but they don't affect the emulated programs at all,
+just the quality of the emulation "output". These options can also
+be toggled at run-time without rebooting the emulation.
+
+
+Sound
+
+Internal Hatari sound handling and the SDL_mixer sound thread
+libALSA sound processing can account up to 1/3 of the Hatari CPU usage
+in normal ST/STE emulation. Disabling sound will get rid of that.
+Using low sound frequency or one matching your sound card may also help.
+Best is if you disable also background music from the programs you run
+in Hatari as this can significantly reduce the number of generated
+interrupts.
+
+
+Frame skipping
+
+Screen rendering can take noticeable amount of CPU time. The default
+Hatari "auto" frame skipping should be used unless there's a good
+reason not to. It will skip converting and showing some of the frames
+if there's not enough time for them.
+
+
+Also, if your monitor refresh frequency is lower than the selected
+Hatari monitor frequency (e.g. LCD monitors usually use 60Hz whereas
+Atari monochrome monitor uses 71Hz), you should use frameskip of one.
+The reason is that if your SDL library uses VSync to synchronize the
+output to screen (like OSX one?), with zero frame skip that forces the
+emulation to run slower than a real Atari. If SDL doesn't use VSync,
+Hatari does redundant work to convert frames you can't see.
+
+
+Zooming
+
+If you are not using frame skip, disabling zooming can have
+noticeable improvement on performance. You can do this by specifying
+suitably low "Max zoomed" resolution (--zoom
+1 command line option sets it to 320x200). If you still want to
+have a nice fullscreen mode, you should rather add the right resolution
+mode-lines (e.g. "320x200") to your xorg.conf file. If you still want
+to use zooming, disabling borders may help a bit.
+
+
+Spec512 color handling
+
+Handling Spec512 color modes which change the ST/e palette constantly
+takes some extra CPU. If you have problems with CPU usage in such
+screens and you care more e.g. from the sound quality than visuals, you
+can disable the Spec512 mode handling by zeroing the threshold for that
+with the --spec512 0 option.
+
+
+Statusbar and drive LED
+
+If your version of libSDL uses VSync to synchronize the screen output,
+drawing of the statusbar or the drive LED may have some minor impact
+on performance too. Normally they shouldn't.
+
+
+
+Measuring the performance
+
+
+There are a couple of ways to monitor and measure Hatari performance.
+
+
+By default Hatari has Statusbar visible and automatic frameskip
+enabled. When Hatari has enough time that it can sleep a little each
+frame, the statusbar frame skip ("FS") value keeps at zero. If Hatari
+is completely busy, it will increase to the maximum specified
+(automatic) frame skip value.
+
+
+Hatari has also a facility to measure FPS i.e. Frames Per Second.
+Just enable the --fast-forward option
+on command line (or use the corresponding keyboard shortcut), and
+after a while, press the "Pause" key. Whenever Hatari emulation is
+paused, Hatari will output on console how many VBLs it could show per
+second along with some other numbers.
+
+
+It depends on what you want to measure, but usually it's best to
+disable sound and set high frame skip like
+--sound off --frameskips 60 so that
+the associated external overheads are minimized. E.g. video output
+can on some platforms do VSync and measurements would then show
+your monitor refresh frequency instead of actual Hatari performance.
+
+
+On Unix systems with times() function
+call, only the time spent by the Hatari process itself is measured.
+On other systems much less accurate SDL "wall clock" timings are
+used. To make latter more accurate you could use also
+--run-vbls option to specify how many
+VBLs Hatari should run before it exits. In this case it's best to
+either have the test-case run automatically from the AUTO-folder or
+given as memory snapshot to Hatari with the frame skip set equal to
+the VBL count.
+
-That's all for the moment.
-May the fun without the price to be with you ;-) !
+Note that the numbers can fluctuate quite a bit, especially
+when the SDL timings are used, so for (statistically) reliable numbers
+you may need to repeat the measurement several times. You should of
+course make also sure that the system doesn't have any other activity
+at the same time you're making the measurements.
