Did you follow a wiihacks guide? If so, perhaps the question is better-served asking in that guide (only if you followed it). If you didn't follow it, perhaps you should?
I am using DIOS MIOS 2.6 (USB HDD) game is booting fine but when I disconnect the controller the game hangs. Also One of my friends console has strange problem GC Controller works on USB Loader GX but not in GC Games. Any idea how to fix this ?
Yes I Have followed guides. Everything works fine other gamecube games working fine. Only Mario sunshine has this problem. Also My friend's wii has all latest cIOSes and Dios Mios 2.6 GCN Game boots fine but GC Controller only works in USB Loader GX not in GC Games in DIOS MIOS.
