Wii:Custom Themes

This tutorial will tell you how to theme your Wii menu, USB Loaders, and Homebrew Channel

DO NOT CONTINUE WITH THIS GUIDE UNLESS YOU HAVE ADEQUATE BRICK PROTECTION, SPECIFICALLY BOOTMII AND PRIILOADER!

MyMenuifyMod has built in safety features to prevent from installing bad or corrupt Wii Menu themes, so please opt to use it instead of other theme installation homebrew.

Do not use any other version of ThemeMii than the one linked here, as ThemeMii Mod allows you to make a theme for Wii Menu version 4.3, other versions may not.

Wii Menu Theming

Only install themes on your Wii that have been formatted specifically for its version and current region. Installing themes from the wrong version or region on your Wii will cause a brick. This tutorial will tell you how to create a .csm file that is safe to install.

Before proceeding, it helps to know the difference between .MYM and .CSM as file formats when used in Wii Menu theming. While the MYM is made by the theme creator which can then be shared around, the CSM is the result from building a MYM into a system menu. In other words, MYM mainly just holds assets - the actual system menu itself that needs to be installed comes seperate.

Theme Sources

• Wii Theme Team Creations (.mym file distribution)
• Wii Theme Google Drive (.mym file distribution)
• GBAtemp Other Files for Wii (.mym file distribution)
• Wii Themer (online theme builder for specific versions and regions, ready to install .csm themes)

Requirements

• An SD Card or USB drive
• A Windows/macOS/Linux PC with an Internet connection
• MyMenuifyMod
• ThemeMii Mod (direct download)

Building a Theme

If you don’t want to go through the hassle of using an external program to build a theme, you can also download a prebuilt theme from Wii Themer and skip to Theme Installation.

1. Once you've downloaded the theme you want, and checked that its the right one for your System Menu version & region, extract the ThemeMii mod .zip and open the application
2. Go to Tools -> Download Base App > Version of your Wii Menu > Region of your Wii Menu
3. You'll get a prompt asking you to enter a value to create a key. Enter what it says, and it will create a key that will be used to decrypt the Wii Menu contents from Nintendo’s servers.
4. A file selection will appear asking you where to save the .app file, save it in the directory ThemeMii is in
5. Go to File -> Open then go to where your .mym is
6. Press Create csm and go to where you want to save your .csm, give it a bit to build your theme
7. You'll get a pop up asking if you want to save the .mym, press No
