My Wii no longer reads Gamecube discs

I was working on getting my gamecube isos to work on my wii for about 4 hours yesterday, and after installing tons of crap and screwing around I finally gave up. I just decided to play one of the games I actually own on a disc. I inserted my Super Smash Bros Melee disc into the Wii, and started it up from the disc channel. Nothing came up, just a black screen. I'm not using a loader or anything, its my actual disc that I'm starting up from the Wii's disc channel. I don't know what I did, but my Wii no longer reads gamecube games. I decided to reformat my Wii to see if it would set some of the files I screwed up to default and I STILL get the black screen when inserting a gamecube disc. I have no idea of what I should do. It can also read Wii discs just fine, its only when I try to start up a gamecube game. Is there anything I could do about this or is my Wii just semi bricked permanently?

 

Well, I don't have the applications on my SD card anymore, so how would I uninstall it? Is there an application that will do a fresh reinstall to the factory settings?
