Michniewski has updated his SNES9x port to Wii and Gamecube once again.

Changes:

– source is now available on google code http://code.google.com/p/snes9x-gx/
– added: option to disable AA filtering (snes graphics ‘crisper’, AA now default OFF)
– added: mapped zooming and turbo mode to classic controller
– added: preliminary usb support (loading)
– changed: sram and freezes now saved by filename, not internal romname. If you have multiple versions of the same game, you can now have srams and freezes for each version. A prompt to convert to the new naming is provided for sram only.
– changed: by default, autoload/save sram and freeze enabled
