Ive got the full versions of duke nukem 3d atomic edition and quake 3, plus openarena, doom (shareware) and they all work flawlessly. so far ive hacked my N900 quite a bit: -modified LED colours and vibrations -removed boot video (can also use custom video, but i prefer none) -added custom profiles with tweakr -made camera button and proximity sensor shortcuts to task manager/phone -customized operator name -added 'reboot' function to power button
