snes9xgx/source/snes9x/apumem.h
dborth fb27030208 [Whats Was New 002 - July 21, 2008] 
- added: classic and nunchuk support
- added: all controllers can now be configured
- added: GC version (untested)
- changed: mappings are no longer stored in SRAM, but in config file. 
           This means no per-game configurations, but one global 
           config per controller.
- one makefile to make all versions. (thanks to snes9x143 SVN)
