My friend's Wii has a WiiKey installed (1.9g). My own Wii also has a WiiKey installed too, but I updated the firmware to 1.9s before playing Mario Kart and I wasn't prompted to update, presumably because 1.9s has an update blocker feature. My friend tried to play the game for the first time and he updated from the disc and now his Wii won't play any backups at all. Does anyone know what the problem might be, or what he could do to fix it? I told him to try upgrading the WiiKey to 1.9s, but he emailed me saying it didn't work. Thanks in advance to anyone that can help.
