Oh, my bad. That's weird cause my buddies Wii that was modded a couple of weeks ago doesn't. He apparently has to go to a channel called Gecpro (Or something like that) and then load the disks. If he just trys to load the disk from the Wii Menu screen he gets an error message and has to reset his system.
That is because he has games that are "Trucha signed", that is, the games have had some sort of customization done to it, also and his wii has been updated to 3.3 and so he would need to load it with GeckoOS.
