I really need some help. So i have my wii softmodded with the homebew channel and i have been running GBA, SNES, N64 emulators on it fine. But i really wanted to get a wii game. So i downloaded the ISO for super smash bros brawl and put it on a usb that was formatted to wbfs with wbfs manager but when i put the usb with the file on it into the wii and go to the homebrew channel and select "usb loader gx" that i put onto the SD card it will load with the game in the list and everything. but when i click on it it shows the normal disk start menu with the art and the start button but when i click start it goes black for a second and then takes me back to the homebrew screen. I have tried changing the setting before i click start but nothing works! I really need help. Please reply and help me out.
