Porting id Software's classic Doom game to a new and significantly limited platform is a hacker's relief from boredom and an open door to fame. Now some crazy dudes have managed to write a playable port
running on iPod Linux (see screenshots). It still lacks certain features such an overhead map and weapon switching. But who cares as long as you can shoot some hideous green-eyed monsters in the face?
This port only works on 1-4G's and Mini 1G/2G. So we're still fantasizing about playing Doom on the iPod Shuffle.
