Have you managed to solve your Wii problem?
I'm trying to recover a Wii from error 003
Mario Kart Wii and Carnival Games worked perfectly with autoboot
But when I try to run smash bros brawl, it shows a message "Please insert the Super Smash Bros Brawl Game Disc"
It seems that Brawl doesn't work when you change the game ID
Edit: this happens when you try to use an NTSC Super Smash Bros Brawl image. You have to use a PAL image. But it will only work on PAL Wiis. On NTSC Wiis, you will have to swap discs.
