not sure if this is the right forum bit for my question to go in but anyway;

ive got a chipped wii with a d2pro and the latest chip firmware. my wii is on version 3.3e. ive got quite a few wii games and i thought i would try a gamecube game, so i got a mario kart double dash iso file and burnt it to dvd, it was a ntsc region game and my wii is pal. it didnt work, so i tried burning at a lower speed, and still didnt work, ive checked the chip utility and it says to boot gc game backups etc. on all the disks ive burnt the gamecube bit comes up on the wii menu and i click start and the screen goes black and does nothing.

where am i going wrong, have i just got a bad iso ???

many thanks
