Hi I just got a Korean Wii with 3.2U pre-installed with Wiigator Backup Loader. I'm no expert when it comes to all this but from what I've learnt, changing the firmware to a different region is not a good idea. The system seems to play games fine but the Mii channel doesn't work. I've read that its possible to fix the Mii channel so I might try that. My question is a simple one. Should I give this model back and get a NTSC/U Wii or is this config fine overall? Also, if I do keep this system, should I get a Wiikey2 and mod it - would this make the system a good one?
