Update to v088r16 release. byuu says: Changelog: - fixed BGnxOFS to not cache when MOSAIC is not in effect [fixes Air Strike Patrol "Good Luck" text] - added GameBoy::Interface::Hook for SGB bindings [SGB works again] - do not create bsnes/ folder unless it is absolutely needed (eg you create a save state or state manager archive) - SuperFX works [needed to call system.init() in Interface::Interface()] Last chance for any bug reports, at this point I pretty much consider ethos to be finished. It's shipping without BS-X BIOS game loading support. Sorry, I can't figure that one out.

Update to v075 release. byuu says: This release brings improved Super Game Boy emulation, the final SHA256 hashes for the DSP-(1,1B,2,3,4) and ST-(0010,0011) coprocessors, user interface improvements, and major internal code restructuring. Changelog (since v074): - completely rewrote memory sub-system to support 1-byte granularity in XML mapping - removed Memory inheritance and MMIO class completely, any address can be mapped to any function now - SuperFX: removed SuperFXBus : Bus, now implemented manually - SA-1: removed SA1Bus : Bus, now implemented manually - entire bus mapping is now static, happens once on cartridge load - as a result, read/write handlers now handle MMC mapping; slower average case, far faster worst case - namespace memory is no more, RAM arrays are stored inside the chips they are owned by now - GameBoy: improved CPU HALT emulation, fixes Zelda: Link's Awakening scrolling - GameBoy: added serial emulation (cannot connect to another GB yet), fixes Shin Megami Tensei - Devichil - GameBoy: improved LCD STAT emulation, fixes Sagaia - ui: added fullscreen support (F11 key), video settings allows for three scale settings - ui: fixed brightness, contrast, gamma, audio volume, input frequency values on program startup - ui: since Qt is dead, config file becomes bsnes.cfg once again - Super Game Boy: you can now load the BIOS without a game inserted to see a pretty white box - ui-gameboy: can be built without SNES components now - libsnes: now a UI target, compile with 'make ui=ui-libsnes' - libsnes: added WRAM, APURAM, VRAM, OAM, CGRAM access (cheat search, etc) - source: removed launcher/, as the Qt port is now gone - source: Makefile restructuring to better support new ui targets - source: lots of other internal code cleanup work

Update to v089r09 release. byuu says: Changelog: - SPC7110 data port emulation greatly improved - SPC7110 $480b.d1 emulated (but $4805-4806 does not work right for mode 2 decompression yet) - MSU1 audio output will be muted when the S-DSP FLG ($6c).d6 (mute) flag is set - MSU1 will read filenames from manifest now (defaults to msu1.rom and track-#.pcm if missing ... for now) - bugfixes with MSU1 load state and track seek (and $4804 was wrapping into $4805 to change the track#) - Link coprocessor removed (it was meant for ST018 HLE, which never happened) Notes for things I forgot but need to address: - $4813 needs to be uint7 for the set_data_offset() to not allow reading A23 as set ever (or we can mask) - AbsoluteInput when window doesn't have focus should return -32768, not 0 - need to support input ID lists that aren't linear (0-7), but arbitrary (0,1,6,7 or whatever)

Update to v089r07 release. byuu says: Not even purify makes compatible images for this WIP. Unless you want to figure it out yourself, I'd suggest waiting for an updated tool before using subsequent WIPs. Changelog: - MSU1 initializes data port + audio track to 0 - MSU1 implements audio track error flag on $2000.d3 - manifest.xml now controls file names for cartridge folders ... mostly Regressions: - Super Game Boy support is broken - Sufami Turbo support is broken So, basically Emulator::Interface() now has: void load(const string &manifest); void save(); The first one will analyze the manifest, and call all the ROM + RAM loadRequest() commands necessary to run the game. The second one will call saveRequest() commands on all writable and non-volatile storage (basically if it's a RAM type and has a filename specified, it gets saved to disk.) save() shrinks the size of Emulator::Interface() by hiding information one is unlikely to care about. It also makes it much easier to save. The core auto-calls this when you unload a game as well. So the only time you ever have to worry about it is if you want to save RAM files mid-game (in case you want to do periodic backups in case of a crash.)

Update to v068r07 release. (there was no r06 release posted to the WIP thread) byuu says: New PPU renderer is coming along. Lots of new ideas, especially with regards to the way the background renders in tiles rather than in pixels. That skips the need for tile caching and compares, and it even gets scrolling right. The sprite item+tile lists are computing, but they are not rendering yet. It's a good deal faster for now, obviously, because 90% of the PPU features are missing.
