It's a DVD drive firmware that can be flashed on your Xbox 360 to allow it to play backups, which are basically copied games.
Read the FAQ that's a sticky in this section first. Then, since you'll want to use Jungleflasher, here's a guide to use that: (I just realized I probably shouldn't post that link. You get the guide by getting Jungleflasher, opening the program, and clicking User Guide). http://www.360mods.net/JungleFlasher/JungleFlasher.pdf[/url]. You'll also need the firmware files for the drive you have, but since they're illegal to post here, you're on your own for that . EDIT: Took out a link that may lead to illegal files.
