A couple of games i loaded to my USB hard drive through the wii USB loader haven't been working. Those 2 being Super Smash Bros. Brawl and Super Mario Galaxy. It loads just fine, but after about 20 to 30 seconds, it just...stops. all the other games play just fine. any idea what could be the issue? Edit: I'm using a 500 GB Mybook external hard drive, in WBFS format as a backup loader through USB.
