I have 4.2u firmware, and I just hacked my Wii tonight. I was able to play GH5 shortly after finishing my hacking, but after installing the RB2 DLC wads and unlocking all RB2 DLC (successfully), I'm now unable to play GH5 without doing a system update. I'm using a legitimate GH5 disc. I'm just trying to get all the DLC on GH5 to be marked as 'puchased'...Any tips?
Thanks in advance!
