Jap 3.2J Wii help with things

I have a 3.2J modded japanese wii. (modchip unknown).
No twilight hack and no homebrew channel yet.

I attempted to run Guitar Hero: WT and Rock Band 2 (both i think US copies)(both backups).
I even tried to run a legit Guitar Hero: WT game(didnt work).
My wii doesn't even recognize the disc. It just gives me the question mark, saying disc cannot be read.

I have read around and am not sure what to do. I have put together some ideas, but am not 100% sure.


Would i do an any region changer?
and if do that, what about my current games.

I need help. Thanks.

no back up talks here!!!!!

No modchips here either. This topic looks exactly like another I junkyarded today...
