[quote name='mrchainsaw']Just a warning, don't buy this if you plan to play it on your 360. It technically is compatible but it runs like total shit.[/quote]

This is a pretty good deal for anyone without a Dreamcast. Worst case scenario, you can always just return it, or if it actually arrives in very good condition (yeah, I know, ha ha), you can flip it for a profit.
