Ok so heres the deal, I upgraded recently from 3.3u to 4.1u to get in on that sd menu. When I was on 3.3 everything worked fine. I had no problems whatsoever. I used the guide here http://www.mediafire.com/?xywqdgzmnnw to upgrade to 4.1. I used to use usbloader gx 792 i think it was. I can load active but then when it would get to any show me how video the game would hard lock with no sound. When I powered the wii back on. BOOM. Your system files have been corrupted. (bootmii to the rescue). So this happens every time right? Remember I had NO problems with this game on 3.3. So I update usbloadergx to whatever the latest channel version on the site is. I think 815 or 812 to fix some lockups with NSMBW. I was able to load Active just fine and even watch the show me how video so I said cool it works. I hit home and click wii menu and BAM. System files corrupted. AGAIN. Seriously Ive had to restore my nand like 8 times. None of the times I powered off or exited the game was any data saving, you know accessing system do not power off kinda thing. Can anyone shed some light on why the hell this is happening? I would really appreciate it. This game actually has exercises my tubby ass can handle. Thanks, -Longbaugh.
