Mod makes online play in New Super Mario Bros. Wii possible
New Super Mario Bros. Wii does feature multiplayer, but it’s limited to local play. It was simply impossible to play with a friend online… until now!
Fans have come up with a mod to allow for online multiplayer in New Super Mario Bros. Wii. You can see a demonstration above.
As for how it works on a technical level, YouTube user “MrBean35000vr” explains:
It works by sending a long stream of inputs over the Internet; button presses on a controller. An assigned host dictates RNG (random number generator, random elements in games like which item you get from a box in MKW for instance), and synchronises level loads so that everyone plays the game at the same speed. It also has an adjustable lag threshold, to allow smoother gameplay with people far away with you, at the cost of slight input delay.
There’s no word yet as to when the mod will be widely available. At the moment, its creator is still working through various issues. This is very neat though, and it sounds like online multiplayer could be implemented in other Wii games that have local multiplayer.
