I bought a brand new Wii at Future Shop in Toronto/Canada 1 week ago, and i just took it to get a chip mod (Wiikey) from someone I know and trust.. so when i go to pick it up, they tested it in front of me, it was fine.. however when I tried to load some games at home, it says unable to read disc.. I tried 3 games (all copied games), all didn't work... until I put in the original Wii Sport then it works.. so I took it back, they found out my new Wii is a bit different than the ones they have modified before.. they still can't figure it out what causes this problem.. right now my Wii can only read retail games but not copied games.. Anyone know what the problem is?? or anyone had the same problem?? please help!!!!!
