Update to v087r14 release. byuu says: Fixed aforementioned issues. [From a previous post: - mul was using r(d) instead of r(n) for accumulate. - mull didn't remove c/v clear. - APU register mask was broken, so SOUNDBIAS was reading out wrong. - APU was only mapping 0x088 and not 0x089 as well. - Halfword reads in CPU+PPU+APU were all reading from the low address each time.] All CPU+PPU registers are now hooked up (not that they do anything.) SOUNDBIAS for APU was hooked up, got tired of working on it for the rest :P I recall from the GB APU that you can't just assign values for the APU MMIO regs. They do odd reload things as well. Also, was using MMIO read code like this: return ( (flaga << 0) || (flagb << 1) || (flagc << 2) ); Logical or doesn't work so well with building flags :P Bad habit from how I split multiple conditionals across several lines. So ... r14 is basically what r13 should have been yesterday, delaying my schedule by yet another day :(

Update to v095r07 release. byuu says: Changelog: - entire GBA core ported to auto function() -> return; syntax - fixed GBA BLDY bug that was causing flickering in a few games - replaced nall/config usage with nall/string/markup/node - this merges all configuration files to a unified settings.bml file - added "Ignore Manifests" option to the advanced setting tab - this lets you keep a manifest.bml for an older version of higan; if you want to do regression testing Be sure to remap your controller/hotkey inputs, and for SNES, choose "Gamepad" from "Controller Port 1" in the system menu. Otherwise you won't get any input. No need to blow away your old config files, unless you want to.

Update to v087r04 release. byuu says: GBA stuff re-added. Only thing missing that was there before is the ARM branch opcode. Since we're going to be staring at it for a very long time, I added a more interesting test video pattern. Went from 6fps to 912fps. Amazing what being able to divide can do for a frame rate.

Update to v087r17 release. byuu says: Emulated GBC sound plus the new extensions to it. I am kind of surprised by how little developers utilized the GBC audio portion. Mr. Driller now has sound effects, and Pinobee no Daibouken has BGM. I still have yet to emulate the GBA extra sound channels and PWM. Need to emulate timers and DMA 2 refresh mode before I can do that. Also, I moved both GBC and GBA audio to use length = data; if(++length == 0); rather than length = 64 - data; if(--length == 0); so that I could return literal values for register reads. I thought there was a good reason we used the latter version, but I can't hear any audible difference even in GBC games, so oh well. Lastly, I think the pattern[++offset] in the wave channel was a bug in the DMG/GBC only. I really, really hope it doesn't apply to the GBA, because that will make bank selection a serious pain in the ass.

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
