Im not sure how many people actually has made use of the nds wireless multilayer, but i recent tried using it with m brothers to no end. It downloads the game to the other system, but that's where the problem begins shortly after is just crashes both systems. I'm not sure if it's because i have a flash cart and he doesn't but it should work since it is wireless. I think it's the game since i tried out a real cart, and the wireless worked fine of course. The flash cart is where the problem is i think or maybe it's the brand as i own a m3....has anyone else experienced a problem like this before?
