Dave Gnukem is a 2D scrolling platform shoot-em-up. It is very similar to (and inspired by) Duke Nukem 1 and has been ported to the PSP by deniska. PSP version features:
1) improved sound fx handling 2) music soundtrack support. I dropped an ogg file from NOIZ2SA as an example; any ogg/s3m/xm/mod file can be used, just name it stage.[ogg/xm/s3m/mod] and drop it in the sounds directory. 3) snaphot mode 4) c/c++ source code with makefile profided for those who want to study/improve the game. 5) the game is very much modable: you can create new levels with the windows version editor and edit the game’s graphics.
