If you've modded your Nintendo Wii and installed the Wii Homebrew Channel, then you might see the following message when loading a game disc:

Error #002
An error has occurred.
Press the Eject Button, remove the Game Disc, and turn off the power to the console.
Please read the Wii Operations Manual for further instructions.

It's possible to fix Wii error 002 without updating your entire system and losing the Homebrew Channel.

Information in this article applies to all versions of the Nintendo Wii video game console.

Cause of Wii Error #002

Error #002 usually occurs when there are IOS problems related to game updates. The Wii IOS (not to be confused with Apple's iOS) is the part of the operating system that loads games, and different games require different IOSes. When you launch a game for the first time, the system will automatically download the proper IOS if it isn't already there.

If your Wii is hacked, updating the operating system will break the Homebrew Channel, which is why users typically avoid system updates when the Wii Homebrew Channel is installed. Fortunately, there are Wii Homebrew apps that allow you to obtain the appropriate IOS for a game without updating the system and losing the Homebrew Channel.

Since Wii consoles manufactured after 2011 do not support GameCube games, you may encounter error #002 on a non-hacked console if you try to load a GameCube disc. This error will also occur if you try to play a Wii game made for a different region. To play such games, you must mod your Wii and then install the required IOS files by following the steps outlined below.

How to Fix Wii Error #002

If your console is not hacked and doesn't have the Homebrew Channel installed, then you can try performing a manual system update from the Wii settings menu. For hacked systems, try these fixes:

  1. Reset the console. Press the reset button and try loading the game again to make sure the error wasn't a temporary glitch.

  2. Use Gecko OS. Gecko OS is an application that allows you to play games from different regions and enable cheats for homebrewed Wiis. You can download it from the Wii Homebrew Browser. Once installed, open the program from the Wii Homebrew Channel menu and select Launch Game to load the current game disc.

  3. Use Pimp My Wii. Pimp My Wii is another program you can download from the Wii Homebrew Browser. Select Perform the test and fix problems from the main menu to automatically install all IOSes and non-homebrew-breaking updates. You can also select Manual installation to choose which updates you want if you know which IOS you need for a particular game.

    Pimp My Wii might re-enable automatic update checking for the system, so go into your settings to make sure this feature is disabled.
