                      3: CPU common:
                      4: - Unimplemented features/bugs:
                      5:  - Delay slot handling may fail sometimes (branch end of page, delay
                      6:  slot next page)
                      7:  - Atomical instructions
                      8:  - CPU features should match real CPUs (also ASI selection)

                     10:  - Condition code/branch handling like x86, also for FPU?

                     12:  - Global register for regwptr, so that windowed registers can be
