I'm sorry, I couldn't find the answer searching. If so please link me.
use the region changer and pull the cord out around half way through, it should unlock this secret mode in the wii that disable disk checks, you will know that it worked when you are greeted with an opera error message (completely normal, don't panic) then put in a ps3 disk (doesn't matter which one) and it should ask you to update when it gets to 100%.
your wii should now be able to play burned ps1/2/3 xbox/360 gc and wii games!
