Gamecube backups problem.
As I have learned since the last time I posted, I'm going to keep my post simple and answer questions if I haven't given enough information.
The main problem is, I can barely use any of my Gamecube backups anymore. I have CIOS38 rev 17 installed, and used MIOSpatcher, selecting v8 and pressing X for backup launcher support.
Using GC Backup Launcher and NeoGamma, I get (using the same backup discs, like put the disc in, get one error, take out, put the same disc back in, different error sometimes) 3 or 4 different errors, most of the time being DVD read error 263. I don't know when it happened, but all my games have started doing this. The only one I've managed to get to load is Twilight Princess, and it loads really slowly. The reason I am confounded by all this is EVERY single backup I have used to work PERFECTLY. The same discs are no longer functioning. I've checked the discs, they seem fine, no scratches or signs of breakage or peeling like some old discs do, and I've used the lens cleaner on the drive multiple times, Wii games still work perfectly and I can even get Brawl to load even though it's double layer and I have a launch day Wii. I'm completely at a loss, any help would be rediculously appreciated.
EDIT: Another thing I tried which I forgot to mention is fixing the ISO files to 3GB. I read soem people had luck with that, but it didn't make a difference for me.
