It's been a while, so here is a new release of bsnes. Unfortunately I don't have a full changelog this time. Most of the work went into stabilizing libsnes (which is used by the experimental .NET, Cocoa and Python UIs; as well as by Richard Bannister's OS X port). The Windows binary package now comes with all three variants included: bsnes.exe, the standard version that casual users should run; bsnes-debugger.exe, for SNES programmers and ROM hackers only; and bsnes-accurate.exe, which should not be used by anybody, ever. In all seriousness, bsnes-accurate.exe is bsnes with the dot-based S-PPU renderer. It's twice as slow as the normal build, and you won't really notice any differences except in Air Strike Patrol. It's there for the curious and for any SNES programmers who want to try making some really awesome video demos. Changelog: * OS X port builds once again; now requires gcc44 from Macports * libsnes API finalized * fixed a bug with S-CPU debugger breakpoints * various source cleanup
