So I came across this DooM II total conversion WAD that mirrors GoldenEye 007. It's not really GE007, but it's a cool thing to have on your GP2x. Again, it's a WAD not a full game (Just needs DOOM).
You have to get the one which says "Should run on any DEH supported Port" for Doom Legacy, Boom or Zdoom, but it's a pity since the EDGE version is the best one IMHO.
One thing though: I noticed the necessary .deh file is missing from the zip, so you need to get it from Here (Right click and "Save link as")
