When I try to play a wad installed game (nes, snes etc) the opening screen plays, there is music and everything looks to be working but after about 10 sec the console freezes and a black screen comes up. my wii was originally 3.1. it was modded then upgraded to 4.1. I followed an older larrylje toot (4.1 and under) which i had saved and has worked many times. when i realized that the VC wasn't working I did a bit of research and found the wads may only work for specific firmwares. I downgraded to 4.0 (since i have another wii on 4.0 which plays all my wads fine). Still no luck. I don't know what else to do, any suggestions?
