Changelog:
- emulator/interface: removed unused Region struct
- gba/cpu: optimized CPU::step() as much as I could for a slight
speedup¹
- gba/cpu: synchronize the APU better during FIFO updates
- higan/md, icarus: add automatic region detection; make it the
default option [hex\_usr]
- picks NTSC-J if there's more than one match ... eventually, this
will be a setting
- higan/md, icarus: support all three combinations of SRAM (8-bit low,
8-bit high, 16-bit)
- processor/arm7tdmi: fix bug when changing to THUMB mode via MSR
[MerryMage]
- tomoko: redesigned crash detector to only occur once for all three
ruby drivers
- this will reduce disk thrashing since the configuration file
only needs to be written out one extra time
- technically, it's twice ... but we should've always been writing
one out on first run in case it crashes then
- tomoko: defaulted back to the safest ruby drivers, given the optimal
drivers have some stability concerns
¹: minor errata: spotted a typo saying `synchronize(cpu)` when the CPU
is stopped, instead of `synchronize(ppu)`. This will be fixed in the v104
official 7zip archives.
I'm kind of rushing here but, it's really good timing for me to push out
a new official release. The blocking issues are resolved or close to it,
and we need lots of testing of the new major changes.
I'm going to consider this a semi-stable testing release and leave links
to v103 just in case.

Changelog:
- Master System: merged Bus into CPU
- Mega Drive: merged BusCPU into CPU; BusAPU into AU
- Mega Drive: added TMSS emulation; disabled by default [hex\_usr]
- VDP lockout not yet emulated
- processor/arm7tdmi: renamed interrupt() to exception()
- processor/arm7tdmi: CPSR.F (FIQ disable) flag is set on reset
- processor/arm7tdmi: pipeline decode stage caches CPSR.T (THUMB mode)
[MerryMage]
- fixes `msr_tests.gba` test F
- processor/arm7tdmi/disassembler: add PC address to left of currently
executing instruction
- processor/arm7tdmi: stop forcing CPSR.M (mode flags) bit 4 high (I
don't know what really happens here)
- processor/arm7tdmi: undefined instructions now generate Undefined
0x4 exception
- processor/arm7tdmi: thumbInstructionAddRegister masks PC by &~3
instead of &~2
- hopefully this is correct; &~2 felt very wrong
- processor/arm7tdmi: thumbInstructionStackMultiple can use sequential
timing for PC/LR PUSH/POP [Cydrak]
- systems/Mega Drive.sys: added tmss.rom; enable with cpu version=1
- tomoko: detect when a ruby video/audio/input driver crashes higan;
disable it on next program startup
v104 blockers:
- Mega Drive: support 8-bit SRAM (even if we don't support 16-bit;
don't force 8-bit to 16-bit)
- Mega Drive: add region detection support to icarus
- ruby: add default audio device information so certain drivers won't
default to silence out of the box
