My friend bought a new Wii with this serial LU39xxxx065. He upgraded to 4.2U when he sets up internet. He had hard time to mod it. Finally it works with Nerogama v7. But he can not run from backup disk, he gets error 1101 when he tries to play the disk. I search for LU65 but did not find anything. Would someone please tell me it is LU65 that has been discussed and can he play with backup disks or he can only use USB. Someone/where mentions with CIOSCORP, it can read backup disk from disk channel. Thnx.
