Ok, thanks for the awnsers... seems kinda weard to me, that that there aint any emulators or anything to play old / light windows games... (example GTA 1 etc etc) tho, maybe some day...
Oh, but GTA IS available with the Morphgear emulator.
There is also ICBM, Space Invaders, Pac-Man, DigDug, Mappy, Ms Pac-Man, etc etc. I have all these games on my device and they are awesome!!! Not freeware though. You can also find Doom, Quake I & II, Wolfenstein 3D, Warcraft II, Stygian Abyss (Yes, I have it and it's identical to the pc version), Descent, Age of Empires and various others. Just do a google search.
