snes roms dont run well on a dreamcast. but nes is good and genisis is ok.
it is worth it though, there are enough fun games to justify the 40 dollars and games can be downloaded and burned easily.
the other more expensive route is a modded xbox. They are excellent for playing emulated games even up to n64 and psx and can play many downloaded movie formats, but the cost is significatly more.
