X-band was great while it lasted. Too bad the owner was in it for the money. Once he got his cash he closed shop. X-band allowed you to play SNES and Genesis games online. Street Fighter, Mortal Kombat, Killer Instinct, Mario Kart were a few of the many available games. It also included an email system, player ranking, personal win/loss score system, chat mode, and other features. The battery(memory) in most X-bands expires in 3-5 years of non usage.
