Nintendo Disc Date

This outputs the date your GameCube, Wii, or Wii U disc was manufactured.

To use, put in the 8 character code on the back of your disc.

Also check out the Wii Remote Date tool as well.
Area circled in yellow: the 8-digit code you run through this tool.
Area circled in red: the revision code. If your disc says 0A-1, 0A-2 on it, or ANYTHING that does not say 0A-0, please join the RiiConnect24 Discord server and tell us the code and game you see this on in the #wii channel.
