Doom was one of my first PC games and I loved it. With the technology progressing, people are trying to out do themselves. If someone made a fully working web server implanted into a fly, porting Doom to iPods doesn't seem so strange. iDoom can be installed on any iPod that runs the iPodlinux platform. iPodlinux currently only supports third generation iPods, but the community forums offer good hacks for other iPods. As you probably presume, installing all of these software packages to your device will ruin your warranty. For the downloads, as well as some screenshots and videos, do visit the iDoom site.
