Update to v103r21 release. byuu says: Changelog: - gb: added TAMA emulation [thanks to endrift for the initial notes] - gb: save RTC memory to disk (MBC3 doesn't write to said memory yet; TAMA doesn't emulate it yet) - gb: expect MMM01 boot loader to be at end of ROM instead of start - gb: store MBC2 save RAM as 256-bytes (512x4-bit) instead of 512-bytes (with padding) - gb: major cleanups to every cartridge mapper; moved to Mapper class instead of MMIO class - gb: don't serialize all mapper states with every save state; only serialize the active mapper - gb: serialize RAM even if a battery isn't present¹ - gb/cartridge: removed unnecessary code; refactored other code to eliminate duplication of functions - icarus: improve GB(C) heuristics generation to not include filenames for cartridges without battery backup - icarus: remove incorrect rearrangement of MMM01 ROM data - md/vdp: fix CRAM reads -- fixes Sonic Spinball colors [hex\_usr] - tomoko: hide the main higan window when entering fullscreen exclusive mode; helps with multi-monitor setups - tomoko: destroy ruby drivers before calling Application::quit() [Screwtape] - libco: add settings.h and defines to fiber, ucontext [Screwtape] ¹: this is one of those crystal clear indications that nobody's actually playing the higan DMG/CGB cores, or at least not with save states. This was a major mistake. Note: I can't find any official documentation that `GL_ALPHA_TEST` was removed from OpenGL 3.2. Since it's not hurting anything except showing some warnings in debug mode, I'm just going to leave it there for now.

Update to release v000r08. byuu says: Changelog: - rewrote sprite rendering, grabs first ten sprites, draws them in revere order of a: X-index, b: OAM appearance order - simplified tile decoding to use less variables - added MBC3 emulation (for now, RTC is always enabled) - STOP can be broken via joypad IF, this may not be correct though (it may trigger even without P10-13 being modified) - cleaned up all MBC emulation to use masks instead of ranges - MBC2 uses 512-byte table now, ignores high 4-bits. Easier this way I guess - tools menu temporarily has a console tracer enable option - some other stuff No real visible improvements :(

Update to v096r03 release. byuu says: Changelog: - fixed icarus to save settings properly - fixed higan's full screen toggle on OS X - increased "Add Codes" button width to avoid text clipping - implemented cocoa/canvas.cpp - added 1s delay after mapping inputs before re-enabling the window (wasn't actually necessary, but already added it) - fixed setEnabled(false) on Cocoa's ListView and TextEdit widgets - updated nall::programpath() to use GetModuleFileName on Windows - GB: system uses open collector logic, so unmapped reads return 0xFF, not 0x00 (passes blargg's cpu_instrs again) [gekkio]

Update to release v000r06. byuu says: Added MBC1 emulation, although battery RAM doesn't save or load to disk yet. Made up a fake MBC0 which is really just saying 'no MBC', for consistent handling of all MBCs. Added bumpers to stop ROM/RAM out of bounds accesses. Added STAT interrupts for LY coincidence, Vblank and Hblank (not for OAM access yet, I don't know the timings.) Fixed timer interrupt [Jonas Quinn] Made all interrupts call a CPU function instead of just setting a flag for better control (to allow below addition.) Added HALT and STOP emulation, the latter permanently locks the Game Boy for now. The former breaks on interrupts. Rewrote all the rendering code to suck 50% less, though it's still absolutely miserable and scanline-based. Added pixel-level horizontal scrolling to BGs. Fixed OBJ rendering error that was making them render upside down (I was flipping to compensate before.) Added OBJ 8x16 mode. Added OBJ priority support. Added window (but it's broken to all hell on Mega Man II.)

Update to v095r08 release. byuu says: Changelog: - added preliminary WASAPI driver (it's really terrible, though. Patches most welcome.) - all of processor/ updated to auto fn() -> ret syntax - all of gb/ updated to auto fn() -> ret syntax If you want to test the WASAPI driver, then edit ui-tomoko/GNUmakefile, and replace audio.xaudio2 with audio.wasapi Note that the two drivers are incompatible and cannot co-exist (yet. We can probably make it work in the future.) All that's left for the auto fn() -> ret syntax is the NES core and the balanced/performance SNES components. This is kind of a big deal because this syntax change causes diffs between WIPs to go crazy. So the sooner we get this done and out of the way, the better. It's also nice from a consistency standpoint, of course.
