Update to v087r15 release. byuu says: Added linear (eg non-affine) sprite rendering, 4bpp and 8bpp with hflip and vflip. Nothing else. You can now see the Nintendo logo and Gameboy text at the end of the BIOS. It's a start =)

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 v093r11 release. byuu says: Changelog: - GBA: SOUND_CTL_H is readable, fixes sound effects in Mario&Luigi Superstar Saga [Cydrak] (note: game is still unplayable due to other bugs) - phoenix/Windows: workaround for Win32 API ListView bug, fixes slot loading behavior - ruby: added udev driver for Linux with rumble support, and added rumble support to existing RawInput driver for XInput and DirectInput - ethos: added new "Rumble" mapping to GBA input assignment, use it to tell higan which controller to rumble (clear it to disable rumble) - GBA: Game Boy Player rumble is now fully emulated - core: added new normalized raw-color palette mode for Display Emulation shaders The way rumble was added to ethos was somewhat hackish. The support doesn't really exist in nall. I need to redesign the entire input system, but that's not a change I want to make so close to a release.

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 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

Cydrak is absolutely amazingly awesome and patient. This really wouldn't be happening without him. Also fixed some things from my end, including greatly improved sprite priorities, and a much better priority sorter. Mr. Driller looks a lot better now.
