Corrupt System File

Hey guys and gals. So, I have a 4.2 system menu wii and have been running HBC with no problems for about a year. That is until last night. I was playing Super Paper Mario and I saved my game and then pressed the "home" button and clicked "return to system menu". My wii then kinda froze for a few seconds and a black screen appeared saying "Your system files are corrupt. Please refer to the operations manual."

So, I restarted my wii using the reset button and the same message appeared immediately after you press "A" to get out of the introduction screen. I have found a workaround, but it is still a pesky bug that I would like to fix. If I restart the wii during a game and don't press "A" to bypass the intro screen (i.e. wait until it automatically goes past the screen) everything works fine.

At first I thought that the Super Paper Mario save file must be corrupt, so I backed it up and then deleted it from the system memory. That didn't help and I actually don't think that is the problem

Now a brief background story. Last night, before this happened, I went out and bought a new wii controller. The one I bought has the wii motion built into it. When I get back home I start playing Super Paper Mario with my old controller and then look over and see the new one. So I press "home" and reconnect my wiimote in order to sync the new one as player 1. I then play for 10 minutes, save the game, press home to return to the system menu and the above occurs. For some reason, I think that this new controller is the culprit. My old official wiimote automatically syncs with my wii at startup, but the new one it seems like I have to reconnect it every time in order to use it.

The only other changes made to the wii last night, before this happened, were:

1. I changed the position of the sensor bar from top of tv to bottom in Wii menu settings;
2. I increased the wii sensor bar's sensitivity;
3. I turned off WiiConnect 24
4. Bought a new Wii Controller (with built in wii motion plus) and tried to synch it as player one.

Any help would be greatly appreciated.

You haven't installed any themes or custom channels recently? If you have, it could be them...

Other than that, it could perhaps be a mail brick, but I don't really know much about them I'm afraid. You should try to boot your Wii in "maintenance mode" (google for instructions). If that works, I believe that means it may be a mail brick.

Well, I got it working but I am still trying to figure out why the hell it happened just to appease my curiosity. As I drove home from lunch after typing the OP I realized that I never permanently synched the new Wiimote. Instead, I was using it by synching the temp way (i.e. home, controller reset, hit buttons 1 & 2 simultaneously). Then I would use that same Wii controller that I just temporarily synched to exit out of the game and back to the system menu. When I would try and do that the new controller would no longer be synched and mashing any of its buttons would just result in four blinking blue lights and a black screen telling me that my System files are corrupt.

Now that I have permanently synched the new controller everything works fine.

Very odd, but I guess I am just glad that it is not bricked because my backup NAND is in the black-hole abyss of my most recent HDD failure. Creating a new NAND backup tonight. :)

Glad you got it fixed. Seems strange, but at least it was fixable.
