/**********************************************************************************
Snes9x - Portable Super Nintendo Entertainment System (TM) emulator.
[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)

[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)
