snes9xgx/source/snes9x/port.h
dborth 65984b9102 [What Was New 004 - August 5, 2008] 
- 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
