Mednafen v0.9.33 WIP Changelog:

- The XBox 360 controller's "guide" button is now mappable and usable under MS Windows. - Rewrote the simple interpolation pixel shaders to fix problems with diagonal lines of graphics distortion. - Rotation(via ALT+O) no longer breaks the image horribly when used with a multiple-horizontal-resolution source image(emulation modules that can produce such an image include pce, pce_fast, pcfx, psx, and snes). - Added support for per-module settings overrides(specified via placing settings in files named such as "nes.cfg", "pce.cfg", "pce_fast.cfg", etc.). - Reduced the maximum supported sound output rate from 1048576Hz to a much more reasonable 192000Hz(significantly eases proper sound processing algorithm design and testing). - Various debugger bugfixes and refactorings to fix design flaws; save-states should now work in step mode with PC-FX and PC Engine emulation without causing crashes. - GB: Added support for entering "GameShark" cheats in the cheat interface. - NES: Added support for entering "Pro Action Rocky" cheats in the cheat interface. - PCE: Removed support for the "enhanced" PSG revision, and the default PSG revision setting is now "match"(HuC6280A for SuperGrafx games and HES playback, HuC6280 for everything else). - PCE, PC-FX: Revamped sound resampling and processing to be much higher-quality. - PS1: Added limited support for entering "GameShark" cheats in the cheat interface(not every code type is supported, and some cheats may not work properly). - PS1: Improved accuracy(and quality) of the CD-XA ADPCM resampling algorithm per tests on a PS1. - PS1: Reworked sector buffering and XA ADPCM playback per tests on a PS1; fixes problems with voice cutoff in "Breath of Fire 4" and probably some other games, and fixes the corrupted boss graphics problem in "Captain Commando". - SNES: Added support for Game Genie codes.
