Update to 20100808 release. byuu says: This fixes libsnes and debugger builds, and collapses bsnes/ppu/bppu to bsnes/ppu and bsnes/dsp/sdsp to bsnes/dsp. It also introduces bsnes/sync.sh, which will synchronize all of asnes/ with bsnes/, excepting the custom speed-focused modules. So far, that's bsnes/ppu (scanline renderer) and bsnes/dsp (state machine.) Should make keeping the two ports in sync much, much easier. It's basically the same thing as before, only you run sync.sh and have a few duplicated folders now. May make it clearer by creating a stub/ or src/ folder inside bsnes to do all of the copying, so that you only see the custom folders in bsnes/' root directory.

Update to v068r15 release. byuu says: This adds a new "Effect Toggle" window to the tools tab list. There's no menu entry for it yet, oversight, but you can go to another tool and tab to it. The effect toggle window lets you toggle background/OAM layers on a per-priority basis and DSP sound channels. This only works with the compatibility and performance cores, because I'm not going to allow accuracy-violating hacks like that into the core. Non-essential icons have been removed, there's six of them left at the moment. I am too much of a consistency guy to only have some scattered around. I know other apps do that, but I'm not going to do that, and I grow tired of trying to hammer in icons that don't really represent the actions. Anyway, it still looks pretty good I think.

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 v074r11 release. byuu says: Changelog: - debugger compiles on all three profiles - libsnes compiles on all three platforms (no API changes to libsnes) - memory.cpp : namespace memory removed (wram -> cpu, apuram -> smp, vram, oam, cgram -> ppu) - sa1.cpp : namespace memory removed (SA-1 specific functions merged inline to SA1::bus_read,write) - GameBoy: added serial link support with interrupts and proper 8192hz timing, but obviously it acts as if no other GB is connected to it - GameBoy: added STAT OAM interrupt, and better STAT d1,d0 mode values - UI: since Qt is dead, I've renamed the config files back to bsnes.cfg and bsnes-geometry.cfg - SA1: IRAM was not syncing to CPU on SA-1 side - PPU/Accuracy and PPU/Performance needed Sprite oam renamed to Sprite sprite; so that I could add uint8 oam[544] - makes more sense anyway, OAM = object attribute memory, obj or sprite are better names for Sprite rendering class - more cleanup
