Update to v097r15 release. byuu says: Changelog: - higan now uses Natural<Size>/Integer<Size> for its internal types - Super Famicom emulation now uses uint24 instead of uint for bus addresses (it's a 24-bit bus) - cleaned up gb/apu MMIO writes - cleaned up sfc/coprocessor/msu1 MMIO writes - ~3% speed penalty I've wanted to do that 24-bit bus thing for so long, but have always been afraid of the speed impact. It's probably going to hurt balanced/performance once they compile again, but it wasn't significant enough to harm the accuracy core's frame rate, thankfully. Only lost one frame per second. The GBA core handlers are clearly going to take a lot more work. The bit-ranges will make it substantially easier to handle, though. Lots of 32-bit registers where certain values span multiple bytes, but we have to be able to read/write at byte-granularity.

Update to v095r05 release. byuu says: Changelog: - GBA: lots of emulation improvements - PPU PRAM is 16-bits wide - DMA masks &~1/Half, &~3/Word - VRAM OBJ 8-bit writes are ignored - OAM 8-bit writes are ignored - BGnCNT unused bits are writable* - BG(0,1)CNT can't set the d13 - BLDALPHA is readable (fixes Donkey Kong Country, etc) - SNES: lots of code cleanups - sfc/chip => sfc/coprocessor - UI: save most recent controller selection GBA test scores: 1552/1552, 37/38, 1020/1260 (* forgot to add the value to the read function, so endrift's I/O tests for them will fail. Fixed locally.) Note: SNES is the only system with multiple controller/expansion port options, and as such is the only one with a "None" option. Because it's shared by the controller and expansion port, it ends up sorted first in the list. This means that on your first run, you'll need to go to Super Famicom->Controller Port 1 and select "Gamepad", otherwise input won't work. Also note that changing the expansion port device requires loading a new cart. Unlike controllers, you aren't meant to hotplug expansion port devices.

Update to v092r09 release. byuu says: This will be another massive diff from the previous version. All of higan was updated to use the new foo& bar syntax, and I also updated switch statements to be consistent as well (but not in the disassemblers, was starting to get an RSI just from what I already did.) phoenix/{windows, cocoa, qt} need to be updated to use "string foo" instead of "const string& foo", and after that, the major diffs should be finished. This archive is the first time I'm posting my copy-on-write, size+capacity nall::string class, so any feedback on that is welcome as well.

Update to v098r11 release. byuu says: Changelog: - fixed nall/path.hpp compilation issue - fixed ruby/audio/xaudio header declaration compilation issue (again) - cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the file was whitespace overkill) - added null terminator entry to nall/windows/utf8.hpp argc[] array - nall/windows/guid.hpp uses the Windows API for generating the GUID - this should stop all the bug reports where two nall users were generating GUIDs at the exact same second - fixed hiro/cocoa compilation issue with uint# types - fixed major higan/sfc Super Game Boy audio latency issue - fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions - major cleanups to higan/processor/r65816 core - merged emulation/native-mode opcodes - use camel-case naming on memory.hpp functions - simplify address masking code for memory.hpp functions - simplify a few opcodes themselves (avoid redundant copies, etc) - rename regs.* to r.* to match modern convention of other CPU cores - removed device.order<> concept from Emulator::Interface - cores will now do the translation to make the job of the UI easier - fixed plurality naming of arrays in Emulator::Interface - example: emulator.ports[p].devices[d].inputs[i] - example: vector<Medium> media - probably more surprises Major show-stoppers to the next official release: - we need to work on GB core improvements: LY=153/0 case, multiple STAT IRQs case, GBC audio output regs, etc. - we need to re-add software cursors for light guns (Super Scope, Justifier) - after the above, we need to fix the turbo button for the Super Scope I really have no idea how I want to implement the light guns. Ideally, we'd want it in higan/video, so we can support the NES Zapper with the same code. But this isn't going to be easy, because only the SNES knows when its output is interlaced, and its resolutions can vary as {256,512}x{224,240,448,480} which requires pixel doubling that was hard-coded to the SNES-specific behavior, but isn't appropriate to be exposed in higan/video.
