This is a video showing an iPOD 30gig 5g. with ROCKBOX. It comes with Doom, you just need to download the .wad file and put it in a specified folder. Rock Box on the this unit comes very handy as I can play video games for free which is a major plus!!! the Video games that come with the latest RockBox build are pretty entertaining.
