hehehe ye Iv'e been doing the same recently, I installed simcity200 and jammed that for days! same with loads of snes, nes and megadrive games, am currently half way through zero tolerence on the megadrive. some old school game work well on the n900, the older the game the better it seems to work, sonic is a good example, it only needs the arrows and a jump key.

quake 2 however seems to be a bit more "complex" I have banged on and on about how come there's no touch controls like on the iphone even if it's just for looking about but it seems far too many people port the game and then call it quites still waiting for some speedups and a software keyboard for dosbox...
