Ni-fi is local wireless multiplayer. There's an option in the menu to host/join a game, so if you have 2 DSes with nesDS on each, then you can play multiplayer.Godson777 said:Wut the heck is the Ni-Fi Multiplayer? How does it work? I HAVE SO MANY QUESTIONS!!!!
If you only have 1 flashcart, it will still work if you remove the flashcart from the DS after the ROM is loaded (meaning that you can play multiplayer that way rather than having to use 2 flashcarts).
