Hello, I use USB Loader GX 2.0 with my collection of Wii games. There are two of which I downloaded from the internet, Twilight Princess and Kirby's Epic Yarn. There are 11 others which I installed from physical copies I already own. I originally went through and made sure they all worked fine, however they've slowly seemed to fall apart. For example, if I clicked on the Twilight Princess cover on the loader screen, it would freeze up and I would have to restart the system completely. Kirby's Epic Yarn now gets to a white screen after the PLEASE PUT ON WII REMOTE COVER AND USE WRIST STRAP LOL screen. One other game, Carnival Games, has lost some of the sound and eventually reaches a black screen. Do you think that the ISO files have become corrupt somehow, and if so, how could this have happened and how can I prevent it from happening in the future?
