Mednafen 0.9.0 WIP changelog:

April 11, 2010: VB: Changed nominal width in pbarrier 3dmode to 768. Removed stale build files. April 7, 2010: Removed unused PulseAudio option from configure.ac. Genesis: Encapsulated more code in a namespace. April 6, 2010: PCE_FAST: Changed "inc" instructions to the equivalent "add" forms in inline assembly for better performance. April 5, 2010: Replaced MDFN_FastU32MemsetM8() with code that doesn't violate strict aliasing(at least when an array with 32-bit elements is passed...which is not exactly the case in every place it's called), and with inline assembly for x86 and x86_64. April 4, 2010: VB: Fixed graphics output when "vdriver" is set to "overlay", and "vb.3dmode" is set to "anaglyph". Fixed command-line argument "-force_module" handling. PC-FX: Renamed setting "pcfx.adpcm.restrict_range" to "pcfx.adpcm.emulate_buggy_codec", since it now does more than effectively restrict the range, thanks to David Michel's analysis of an official PC-FX ADPCM encoder. April 3, 2010: Settings are now sorted before being saved to disk. Invalid/Unknown settings are now saved back to the configuration file on exit rather than being discarded. PCE: Fixed input port definitions so that Tsushin Keyboard can only be enabled on input port 1(which reduces the number of input mapping settings automatically generated by about 400). PCE: Multitap emulation is now automatically disabled when Tsushin Keyboard is selected on input port 1(TODO: document this fact). NES: Fixed a few memory leaks in filter.cpp.
