Play X-band Modem Bios Online

I remember the X-Band Modem for the Super Nintendo Entertainment System, released by Catapult Entertainment in 1995. It was a peripheral that plugged into the cartridge slot, letting you dial into a service to play certain SNES games against other people online. This was before broadband, so you used your home phone line. The modem itself didn't play games; it worked by modifying the code of supported cartridges you inserted into it, like Mortal Kombat or NBA Jam, to enable network play. The whole setup felt like a glimpse into a future that was still years away for most console players.

You don't control a character; you manage the connection. After subscribing and plugging in the phone line, you boot up a supported game. The modem intercepts the game's normal multiplayer routines, redirecting the data over the phone line to another player doing the same. The main objective is simply to play your favorite competitive games against human opponents who aren't in the same room. Signature mechanics include navigating a graphical interface to find opponents, dealing with the inherent lag of a dial-up connection, which could make timing in a fighting game difficult, and using the service's features like leaderboards and a primitive email system. The pacing is entirely dependent on the game you choose and the quality of your connection. It felt like a technical marvel, even with the occasional screech of the modem and a dropped call right as you were about to win.
