WiiRd is an unofficial cheat engine exclusively for Nintendo's Wii game console, made by a group of talented hardware and software engineers seeking to address the lack of an official cheat device, like Action Replay or GameShark, on Wii. Using GeckoOS, you can use just an SD card to store the codes (using Ocarina built into the program), or go with an optional hardware solution like the USBGecko for real-time code changing.
Regardless, click here to view full instructions on installing WiiRd in your Wii (link opens in a pop-up window/tab so you can easily come back here).

Special instructions are needed to get these types of codes to work with GameCube games. Click here to find out how to do it.

Many more non-size changing codes are available here

Games are listed in alphabetical order and are tested and confirmed before they get posted here.
Remember to read anything that's under Important Info before you use these codes!

Made by
: Sega
Platform: Wii
Information by Link

Important Info:
To change sizes of specific character please use: mswlist.html (JavaScript needs to be enabled).
Default size is 1, double size is 2 and so on. The code should apply WHENEVER a character appears (menus, town, all events).

Problems: this current code seems to have no collissions (collissions means: it doesn't accidently resize something it is not supposed to resize). If you find one: please feel free to e-mail me at link0x@gmx.org and report: please include in the report:
-which characters were resized (scale is not important)
-which event the collission occured
-which object or other character was accidently resized alongside

Information by Link and Y.S.

Important Info:
The data of the Rosalina Size Modifier code is stored fixed. When you enlarge her, enter a stage and return she'll stay enlarged, so it will always apply when Rosalina appears on-screen (even at the beginning of the game or in the outro).
USBGecko users: do not turn on this code while Rosalina is visible on screen - once activated, never deactivate this code!
