Ok so I updated to 4.0 with wanin's' updater, and everything is cool. Homebrew channel works, backup channel works, usb loader works, wad manager works, but I cant run wads from the SD card. I tried the patcher thing but that didnt work either. Oh yeah and one more thing, when you do play something from the SD card, it copies to the system memory, how do you clear the memory? Just restarting the wii?
