I have a Wii version 3.3u. I recently setup the really effective backup loader system to play game backups off a external hard drive. For some reason, I can't play Wii Sports Resort. Could it be that I have to upgrade my Wii? I wonder if keeping your wii at such an earlier version would hobble its ability to play later games? I appears to be the only problematic game aside from maybe Super Smash Brothers.
