I've made an playable version of Quetoo Quake2 port for the N800. The game renders at 320x192 by default, though any can be used by launching the game with f.ex. 'quetoo +set vid_width 400 +set vid_height 240' from xterm and the image is always scaled to fill the whole screen. Looking around works by dragging on the screen.

You'll need to place the quake2 paks to /media/mmc2/quake2/baseq2/. The menu link launches the first level of the full version. To go to other maps, start the game from xterm with 'quetoo +map name_of_map'. (there's an list of all the map names in the same folder that has the quake2 paks atleast on my quake2 cd).

The package and sources are available from http://www2.lut.fi/~thietan1/quetoo/.

The game does not run amazingly fast, but if someone could optimize the ConvertRGBtoYUY2 function in vid_sdl.c, the game could probably run far better.
