Update to v087r26 release. byuu says: Changelog: - fixed FIFO[1] reset behavior (fixes audio in Sword of Mana) - added FlashROM emulation (both sizes) - GBA parses RAM settings from manifest.xml now - save RAM is written to disk now - added save state support (it's currently broken, though) - fixed ROM/RAM access timings - open bus should mostly work (we don't do the PC+12 stuff yet) - emulated the undocumented memory control register (mirror IWRAM, disable I+EWRAM, EWRAM wait state count) - emulated keypad interrupts - emulated STOP (freezes video, audio, DMA and timers; only breaks on keypad IRQs) - probably a lot more, it was a long night ... Show stoppers, missing things, broken things, etc: - ST018 is still completely broken - GBC audio sequencer apparently needs work - GBA audio FIFO buffer seems too quiet - PHI / ROM prefetch needs to be emulated (no idea on how to do this, especially PHI) - SOUNDBIAS 64/128/256khz modes should output at that resolution (really, we need to simulate PWM properly, no idea on how to do this) - object mosaic top-left coordinates are wrong (minor, fixing will actually make the effect look worse) - need to emulate PPU greenswap and color palette distortion (no idea on how do this) - need GBA save type database (I would also LIKE to blacklist / patch-out trainers, but that's a discussion for another day.) - some ARM ops advance the prefetch buffer, so you can read PC+12 in some cases

Update to v087r27 release. byuu says: Changelog: - serialize processor.pc.data, not processor.pc - call CPU processor.setMode() in ARM serialize - serialize BIOS.mdr - support SRAM > 32KB - EEPROM, FlashROM serialize - EEPROM lose nall/bitarray.hpp - noise line feed after envelope - space out PSR read - ST018 needs byte reads fixed (don't align) [fixes HNMS2] - flush sram/eeprom/flashrom to 0 on cartridge load - APU/PPU dont sync back to CPU if syncing for state - fixed APU sync problems in GB/GBC core that could possibly wreck save states as well Quite a lot of little problems there. I believe GBA save states are fixed now.

Update to v087r19 release. byuu says: Changelog: - added FIFO buffer emulation (with DMA and all that jazz) [Cydrak] - fixed timers and vcounter assign [Cydrak] - emulated EEPROM (you have to change size manually for 14-bit mode, we need a database badly now) [SMA runs now] - removed OAM array, now decoding directly to struct Object {} [128] and ObjectParam {} [32] (faster this way) - check forceblank (still doesn't remove all garble between transitions, though??) - lots of other stuff Delete your settings.cfg, or manually change frequencyGBA to 32768, or bad things will happen (this may change back to 256KHz-4MHz later.) 15 of 16 games are fully playable now, and look and sound great. The major missing detail right now is PPU blending support, and we really need to optimize the hell out of the code.

Update to v087r30 release. byuu says: Changelog: - DMA channel masks added (some are 27-bit source/target and some are 14-bit length -- hooray, varuint_t class.) - No more state.pending flags. Instead, we set dma.pending flag when we want a transfer (fixes GBA Video - Pokemon audio) [Cydrak] - fixed OBJ Vmosaic [Cydrak, krom] - OBJ cannot read <=0x13fff in BG modes 3-5 (fixes the garbled tile at the top-left of some games) - DMA timing should be much closer to hardware now, but probably not perfect - PPU frame blending uses blargg's bit-perfect, rounded method (slower, but what can you do?) - GBA carts really unload now - added nall/gba/cartridge.hpp: used when there is no manifest. Scans ROMs for library tags, and selects the first valid one found - added EEPROM auto-detection when EEPROM size=0. Forces disk/save state size to 8192 (otherwise states could crash between pre and post detect.) - detects first read after a set read address command when the size is zero, and sets all subsequent bit-lengths to that value, prints detected size to terminal - added nall/nes/cartridge.hpp: moves iNES detection out of emulation core. Important to note: long-term goal is to remove all nall/(system)/cartridge.hpp detections from the core and replace with databases. All in good time. Anyway, the GBA workarounds should work for ~98.5% of the library, if my pre-scanning was correct (~40 games with odd tags. I reject ones without numeric versions now, too.) I think we're basically at a point where we can release a new version now. Compatibility should be relatively high (at least for a first release), and fixes are only going to affect one or two games at a time. I'd like to start doing some major cleaning house internally (rename NES->Famicom, SNES->SuperFamicom and such.) Would be much wiser to do that on a .01 WIP to minimize regressions. The main problems with a release now: - speed is pretty bad, haven't really optimized much yet (not sure how much we can improve it yet, this usually isn't easy) - sound isn't -great-, but the GBA audio sucks anyway :P - couple of known bugs (Sonic X video, etc.)
