1.1 ! root 1: 950826 bugfix in GenerateDecTab(): LEA.W instructions were generated. ! 2: 950312 New file disk.cc, for (guess what) disk support. Doesn't work yet. ! 3: 950311 Multiplication instructions were generating 16 bit results. ! 4: Sign extension was wrong in some places. ! 5: Removed bugs in the blitter (one word width: ALWM & AFWM and line mode) ! 6: The Kickstart logo looks perfect now. ! 7: Playfield routine should check BPLCON0 instead of BLTCON0 ! 8: 950309 ASR D8,D0 is not a valid instruction. ! 9: Bitplane pointers were not incremented. ! 10: Copper comparison didn't work. COP2LC and bitplane pointers were written ! 11: incorrectly. Fixed. ! 12: Something that bears a striking resemblance to the familiar Kickstart ! 13: logo now appears in my X window! ! 14: 950306 ROR used to set the X flag. Bug fixes in GenerateDecTab. ! 15: More bug fixes in several 68000 instructions. ! 16: Improved blitter. ?????? KS1.3 doesn't seem to set BLTDMOD on a ! 17: line draw. What is this?? ! 18: Fixed stupid bugs in playfield code. ! 19: 950305 fixed bugs in opcode generation and interrupt handling. Implemented ! 20: STOP. Fixed flag settings: Result wasn't masked. Ooops!! ! 21: ADDQ #imm,An doesn't set flags. ! 22: One-shot timer mode didn't work. ! 23: Implemented blitter, doesn't work. ! 24: Some primitive and slow playfield support, only to make the things that ! 25: hopefully will soon appear visible. ! 26: 950304 CIA timers ought to work OK. Copper is emulated. ! 27: Emulator loops infinitely when trying to initialize the console.device ! 28: 950303 experiments with X, figured out how to open a window and draw pixels. ! 29: No graphics emulation yet, though. ! 30: 950301 Nearly all instructions work. ! 31: Fixed supervisor mode stack. ! 32: The memory manager now handles CIA chips. ! 33: 950228 Bug fixes in 68000 code, exceptions and more instructions implemented ! 34: Memory management extended to handle custom chips as well. ! 35: Debugger improved. ! 36: Kickstart passes memory & CPU type test, builds up some system ! 37: structures. ! 38: 950227 MC68000 & little debugger for tracing. It can execute the first couple ! 39: of KS1.3 instructions, but doesn't get past the memory test. ! 40: 950225 Work begun
