Update to v099r12 release. byuu says: Changelog: - fixed FC AxROM / VRC7 regression - BitField split to BooleanBitField/NaturalBitField (in preparation for IntegerBitField) - BitFieldReference removed - GB CPU cleaned up - GB Cartridge + Mappers cleaned up - SFC CGRAM is now emulated as uint15[256] instead of uint[512] - sfc/ppu/memory.cpp no longer needed; removed - purged SFC Debugger hooks for now (some of the operator[] calls were bypassing them anyway) Unfortunately, for reasons that defy all semblance of logic, the CGRAM change caused a slight speed hit. As have the last few changes. We're now down to around 129.5fps compared to 123.fps for v099 and 134.5fps at our peak (v099r01-r02). I really like the style I came up with for the Game Boy mappers to settle the purpose(ROM,RAM) vs (rom,ram)Purpose naming convention. If I ever get around to redoing the NES mappers, that's likely the approach I'll take.

Update to v084r06 release. byuu says: Changelog: - fixed sprite tile masking for 8x16 mode (fixes Zelda: DX sprites) - HuC1 flag sets RAM writable, not RAM enable (fixes Pokemon Card) - removed within<> template, didn't turn out to be all that useful I would be almost certain no games would break by allowing reads when it is disabled, no game would rely on that behavior. I prefer to be overly restrictive. Better to not allow valid behavior than to allow invalid behavior. The latter is what gives us a dozen broken SNES translations.

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.
