Things You'll Need
Instructions
Turn on your Nintendo Wii. There is no way to determine the model or firmware version of your Wii from the outside or inside of the console; you must connect the console to your television and power up the unit.
Navigate to the Wii Options menu. On the main menu, look to the lower left corner and select Wii Options.
Navigate to the Wii Settings menu. Once you are on the Wii Options menu, you will see two options. Select the Wii Options menu located on the left.
Locate the version number. On page one of the Wii Options menu, the version number for your Nintendo Wii will be listed on the top right of the screen. The version number will be two numerals and one letter. The numbers tell you what firmware version you're running; the letter tells you what country your Wii was manufactured for.
