I have a 4.0E Wii. Wiikey. WIth HBC, Gecko, Wad Manager and Coverflow installed. I have downgraded IOS to allow me to run Cover flow from a channel which works brilliant with my Seagate freeagent 250gb drive with over 50 titles on it. The problem is Guitar Hero World tour. When played from the original disc (yes I buy games) I can download tracks (dlc) and save to SD card. When I play from the USB drive it won't allow me to play those titles or download more. Anyone got any ideas?
