X-Band was an online gaming adaptor for SNES and Genesis, in 1995 I believe, and it supported quite a few games. Unfortunately, the concept was more advanced then the technology of the day, and it failed. But they should\'ve done it for PSX and N64, the technology\'s been here for years now. The modemish thingy went in the cartridge slot, and the game hooked to it, then you had to make it dial a number, and you connected to a hub of X-Band users, and set up challenges for MK2 or Mario Kart. It had realtime chat, and a bulletin board to post high scores and the like.
