I only have lite homebrew installed on my system - that is, I've only ever installed the homebrew channel - not DVDx, not bootmii, not anything else - and used it to run a few simple homebrew programs, and maybe Gecko OS every now and then to use codes. Recently, I haven't used it at all - and I have NOT updated to the new System Menu. I was getting ready to play SPORE HERO for a few minutes before heading to work, and accidentally clicked on the WiiWare game next to the disc menu. It came up VERY SLOWLY. I clikced the "-" button to move to the disc channel, and after looking for the disc for a moment, the following message came up: "The system files are corrupted. Please refer to the Wii Operations Manual for help troubleshooting." I freaked out a little bit, and then rest my system. Now it's acting normal. What the hell is going on here? I thought about Uninstalling homebrew channel and formatting my system memory, then updating to the new system menu, but aside from that I can think of no "fix" that will get me clear with Nintendo in case it bricks on me, or if i have bad memory or something. I don't REALLY want to do this though, becasue I'll lose my WiiWare saves for Megaman 9, Onslaght, and world of goo - - and a lot of my other "no copy" saves will be a pain to transfer back without using the homebrew channel. (Bannerbomb pluss savegame installer, i guess?) What usually causes this message? I've deliberately avoided installing any non official IOS files for this very reason, yet it happened anyway. Is it a one off thing, or a big deal that's going to loom it's head soon?
