Wii Error Messages
A Wii Error Message occurs when the Wii encounters an error. There are many error messages on the Wii that have different meanings.
An Error Has Occurred
This is a generic error encountered by a Wii caused mostly because of a dirty or damaged disc inside the Wii console. The best thing to do is check the disc for any scratches or dirt that could cause disc read errors.
More rarely, this could be a problem related to the Wii console's DVD drive being broken or damaged. Repairs might be required if this is the case. (Please add more info)
Insert Startup Disc
This error message is a very rare error that only seems to occur around launch. This indicates an incomplete System Menu is installed. the wii startup disk is now seen as lost media and was only on retail demo wii consoles on retail consoles the idea was scrapped by nintendo.
The System Files Are Corrupted
This error message is usually caused by a banner Brick. When the Wii Menu detects a corrupted or incompatible channel banner, it will crash to this error. More rarely, this can also be caused by editing the Wii System Menu incorrectly or deleting a vital file. If you do encounter this error and want to fix it, use AnyTitle Deleter to delete the channel with the bad or invalid banner. In the case of invalid or deleted System Menu files, launching DOP - Mii to reinstall the system menu via the Homebrew Channel or an autoboot disc can work as well.
The () System File is corrupted
This error message can occur when certain channel files are not found/are corrupted. This message could display if you change the system language to a language that the application does not support, such as trying to launch the NTSC-U/PAL Forecast Channel with Japanese as the system language. This is a result of the system trying to load the Japanese strings, which do not exist.
The error screen will look something like this:
The Opera error message is caused by a corrupt settings menu or installing a System Menu Update from a disc from another region. This is called a semi-brick.
If the error is related to changing the region on your Wii, you can easily fix it by changing the region settings back to the way they were before they were changed. However, it is easy to turn the semi-brick into a full brick. If you do not have BootMii as boot2 or have Priiloader installed, your Wii will most likely be unusable in a full brick.
This channel can't be used.
This error shows up when you open a channel that doesn't match the system region. (For example, opening a Japanese exclusive channel on an EU wii.)
