I use USB Loader DX, and Configurable USB Loader... neither of them work now.
I've tried deleting and reinstalling the virtual console titles and nothing.
I'm assuming it has something to do with the Drive REFUSING to take in discs. It turns on briefly at start up, and the motor runs for a second. I had to turn it on and off 5 times just to get a disc in, and even when it was in, it wouldn't be read... and now I can't get it out. I don't know why it not working would affect the Virtual Console, but maybe it does.
It's really weird... all of the backups load but hang on a black screen and then I'm told to eject a disc. The Virtual Console games load for 10 sec, and then cut to black (the newer ones cut to an eject screen, which is weird for a virtual console title). So, I'm going to get my friend to open up the Wii and see if there's anything blatantly wrong with the disc drive, because as far as I can tell (especially after restoring the NAND, twice, and this error occuring still) this problem is hardware based.
