Thanks for the help.
I bought this chipped set from the shop, so I don't know much about it. The shop ower doesn't seem to know much about all these stuff. I assume they got it from some other supplier.
I've tried updating with the WiiKey 1.9s Jap. The update was sucessful, but I still get the error msg. The games that run previously, still works fine.
Do you know any way I can update my chip to play Mario Galaxy and Smash Bros?
Thanks for all the help, appreciate it.
