Update to v088r07 release. byuu says: (r05 and r06 were save points between large core modifications) I would really appreciate extensive regression testing (especially around SuperFX, Cx4, ST018, DSP-n, ST-01n, NES, GB) at this point. The most critical core changes should be completed now. And it was an unbelievable amount of restructuring. Changelog: - SuperFX core moved to Processor::GSU - SNES::CPU core moved to Processor::R65816 - SNES::SMP core moved to Processor::SPC700 - NES::CPU core renamed to Processor::R6502 - use filestream to load RAM files from interface - save states store SHA256 instead of CRC32 (CRC32 usage removed entirely from bsnes) - nes/ -> fc/ and NES -> FC - snes/ -> sfc/ and SNES -> SFC - SuperFamicom::MappedRAM::copy uses stream instead of data+size - Linux port uses gcc-4.7 (still using only gcc-4.6 subset, so you can make a gcc-4.6 symlink for now if you like.) - all profiles and all targets compile and work properly All eight instruction set cores have been moved to processor/ now. Consistency's a wonderful thing. The last remnants of NES/SNES are now limited to target-ui code; and the nall/(system) folder names. I'm building with gcc-4.7 on my Linux box now because the resultant binaries are up to 20% faster (seriously) than gcc-4.6.

Update to v078r05 release. byuu says: This WIP adds Nintendo Super System emulation, at least of its DIP switches. This is done via XML mapping, like so: <?xml version="1.0" encoding="UTF-8"?> <cartridge region="NTSC"> <name>ActRaiser</name> <rom> <map mode="linear" address="00-7f:8000-ffff"/> <map mode="linear" address="80-ff:8000-ffff"/> </rom> <nss> <setting name="Difficulty"> <option value="0000" name="Easy"/> <option value="0001" name="Normal"/> <option value="0002" name="Hard"/> <option value="0003" name="Expert"/> </setting> <setting name="Lives"> <option value="0000" name="5 lives"/> <option value="0004" name="4 lives"/> <option value="0008" name="3 lives"/> <option value="000c" name="2 lives"/> </setting> </nss> </cartridge> The value field is a 16-bit value. All selected options are ORed together to produce the final DIP switch values. The number of options per setting is unlimited, but there are only sixteen settings allowed (you can't have more settings than you have switches, that's just stupid.) In the example above, d0-d1 controls difficulty, and d2-d3 controls # of lives. d4-d15 appear to be unused, as far as I can tell.

Update to v095r06 release. byuu says: Changelog: - fixed I/O register reads; perfect score on endrift's I/O tests now - fixed mouse capture clipping on Windows [Cydrak] - several hours of code maintenance work done on the SFC core All higan/sfc files should now use the auto fn() -> ret; syntax. Haven't converted all unsigned->uint yet. Also, probably won't do sfc/alt as that's mostly just speed hack stuff. Errata: - forgot auto& instead of just auto on SuperFamicom::Video::draw_cursor, which makes Super Scope / Justifier crash. Will be fixed in the next WIP.

Update to v098r06 release. byuu says: Changelog: - emulation cores now refresh video from host thread instead of cothreads (fix AMD crash) - SFC: fixed another bug with leap year months in SharpRTC emulation - SFC: cleaned up camelCase on function names for armdsp,epsonrtc,hitachidsp,mcc,nss,sharprtc classes - GB: added MBC1M emulation (requires manually setting mapper=MBC1M in manifest.bml for now, sorry) - audio: implemented Emulator::Audio mixer and effects processor - audio: implemented Emulator::Stream interface - it is now possible to have more than two audio streams: eg SNES + SGB + MSU1 + Voicer-Kun (eventually) - audio: added reverb delay + reverb level settings; exposed balance configuration in UI - video: reworked palette generation to re-enable saturation, gamma, luminance adjustments - higan/emulator.cpp is gone since there was nothing left in it I know you guys are going to say the color adjust/balance/reverb stuff is pointless. And indeed it mostly is. But I like the idea of allowing some fun special effects and configurability that isn't system-wide. Note: there seems to be some kind of added audio lag in the SGB emulation now, and I don't really understand why. The code should be effectively identical to what I had before. The only main thing is that I'm sampling things to 48000hz instead of 32040hz before mixing. There's no point where I'm intentionally introducing added latency though. I'm kind of stumped, so if anyone wouldn't mind taking a look at it, it'd be much appreciated :/ I don't have an MSU1 test ROM, but the latency issue may affect MSU1 as well, and that would be very bad.

Update to v097r15 release. byuu says: Changelog: - higan now uses Natural<Size>/Integer<Size> for its internal types - Super Famicom emulation now uses uint24 instead of uint for bus addresses (it's a 24-bit bus) - cleaned up gb/apu MMIO writes - cleaned up sfc/coprocessor/msu1 MMIO writes - ~3% speed penalty I've wanted to do that 24-bit bus thing for so long, but have always been afraid of the speed impact. It's probably going to hurt balanced/performance once they compile again, but it wasn't significant enough to harm the accuracy core's frame rate, thankfully. Only lost one frame per second. The GBA core handlers are clearly going to take a lot more work. The bit-ranges will make it substantially easier to handle, though. Lots of 32-bit registers where certain values span multiple bytes, but we have to be able to read/write at byte-granularity.

Not sure what the hell is going on there. Trace logs of 430MB are not enticing ... So right now: SuperFX, SPC7110 and BS-X cheat by mapping stuff to Cartridge::ROM, RAM still. They need to not do that.
