Update to v097r29 release. byuu says: Changelog: - fixed DAS instruction (Judgment Silversword score) - fixed [VH]TMR_FREQ writes (Judgement Silversword audio after area 20) - fixed initialization of SP (fixes seven games that were hanging on startup) - added SER_STATUS and SER_DATA stubs (fixes four games that were hanging on startup) - initialized IEEP data (fixes Super Robot Taisen Compact 2 series) - note: you'll need to delete your internal.com in WonderSwan (Color).sys folders - fixed CMPS and SCAS termination condition (fixes serious bugs in four games) - set read/writeCompleted flags for EEPROM status (fixes Tetsujin 28 Gou) - major code cleanups to SFC/R65816 and SFC/CPU - mostly refactored disassembler to output strings instead of using char* buffer - unrolled all the subfolders on sfc/cpu to a single directory - corrected casing for all of sfc/cpu and a large portion of processor/r65816 I kind of went overboard on the code cleanup with this WIP. Hopefully nothing broke. Any testing one can do with the SFC accuracy core would be greatly appreciated. There's still an absolutely huge amount of work left to go, but I do want to eventually refresh the entire codebase to my current coding style, which is extremely different from stuff that's been in higan mostly untouched since ~2006 or so. It's dangerous and fickle work, but if I don't do it, then the code will be a jumbled mess of several different styles.

Update to v074r04 release. byuu says: SuperFXBus was inheriting from Bus, in other words using a copy of the same memory mapping subsystem. I've removed that and made it a simple mask, since only ROM+RAM are mapped there.

First version split into asnes and bsnes.

Update to v094r33 release. byuu says: Small WIP, just fixes the timings for GSU multiply. However, the actual product may still be wrong when CLSR and MS0 are both set. Since I wasn't 'corrupting' the value in said case before, then this behavior can only be better than before. Turned the (cache,memory)_access_timing into functions that compute the values; and pulled "clockspeed" into GSU. Also, I'm thinking it might be kind of pointless to have clockspeed at all. Supposedly even the Mario Chip can run at 21.48MHz anyway. Enforcing 10.74MHz mode seems kind of silly. If we change it to just be a "default value for CLSR", then we can just inline the memory access tests without the need for the access_timing functions (literally just clsr?2:1 then) Slight compilation bug: go to processor/gsu/registers.hpp:33 and add reg16_t() = default; I missed it due to a partial recompile. Too lazy to upload another WIP just for that. Probably not worth doing much SuperFX testing just yet, as it looks like they're doing some other tests at the moment on NESdev.
