I've been doing some testing for gaming in linux and tried several different things.

Games for the #Atari, #NES, #GameGear and #Gamecube, with stuff like the NES HD texture packs for Mesen, the #SuperMarioWorld widescreen hack, and #Primehack, which allows mouse and keyboard play for Metroid Prime games.

Other stuff added are several #RPGMaker games using EasyRPG, and the Adobe #Flash Player available in the Discover store if you use KDE.
