Have there ever been any attempts to create this kind of mods? So that it would be theoretically possible to play, for example, Diablo 2 (online only) and Towerfall (single device multiplayer) using local wireless.
This is a great project! But I want quite the opposite -- to convert other types of multiplayer to local wireless.You can use ldn_mitm, this should be perfect for your purpose. It's a Switch homebrew tool that redirects local wireless over networks.
