SNESoIP: It’s Exactly What It Sounds Like


Here’s a cool hack for those of you wishing to play some retro multiplayer SNES games online!

[Michael Fitzmayer] is a resident hacker at shackspace; der hackerspace in StuttgartHe’s come up with this clever little ethernet adapter network-bridge that can share local controller-inputs over the internet. The entire project is open-source, and readily available on github. It’s still in the early stage of development, but it is already fully functional. The firmware is small and will fit on an ATmega8, and by the looks of the component list it’s a fairly easy build.

He’s even integrated a switch mode (hold B and Y during boot), which avoids trying to figure out which controller will be player one! After all, don’t you remember untangling the controller cords, trying to figure out which one is which?

We know you had a favorite controller and would give the other “crappy” one to your guest.

Example video is after the break.

  1. This would only work in instances where game state doesn’t need to be synced. Something like Tetris Attack would never work using just input sharing. This style of network play is also prone to de-syncing just through packet loss.

    Still, it’s pretty nifty.

  2. Pretty cool idea! Seems to work alright but it’s never going to be very accurate because of latency and differences in random game events. You’d have to sync the consoles memory and stuff to overcome this.

  3. Hey!
    Thank you for the comments and the interest in this project. It makes me a little bit proud to see it here on Hack a Day. :)

    Anyways, you guys are right, regarding the latency problem and the issues with random events. But it was a very good (and easy to accomplish) starting point while developing the hardware (within 4 weeks).

    But my personal main goal is to create some kind of server controlled BBS or online game, using homebrew software to handle the incoming and outgoing data. In fact, the controller ports are just serial ports, at least from a technical point of view. A suitable PS/2-to-SNES keyboard adapter is already finished.

    About the XBAND from the mid 90s: It was practically the same technique, but it used RAM patches to avoid the random event issues. This could be done using Romhacks on a flash cartridge. We’ll see. :)

    If you want to help in the development of this project, join us in #retrotardation on euIRC. We’re also working on a similar Gameboy Classic / Super Gameboy project.
