I have HomeBrew installed and HackMii installed using the super smash bros. brawl method, but I'm unsure as to get the usb loader on there so I can play ISO's for games that are on my USB...
problematic task. browse on to bing and yahoo. that will could help!
The best guide I've seen is at the link below. It will help you get Configurable USB Loader installed and working. It takes time, and it's a complicated process, so READ IT CAREFULLY before you do anything. I love USB loaders, since I have kids who constantly destroy discs. However, remember that the law only allows you to do this with games you actually own. Other than that, it's all legal, so have fun!
