Extract text from Wii themes (MYM)
To convert MYM themes to another format, you need ThemeMii or other Game software.
To convert other file formats to the "Console Modding File" file type, you need software like ThemeMii or a similar tool.
The .MYM file type is primarily associated with MyMenuify, a homebrew application used to customize the System Menu of the Nintendo Wii console. These files act as theme scripts or containers, bundling the necessary assets (like TPL textures or standard images) and layout instructions required to modify the Wii's interface.
For most users, a .MYM file is an intermediate step. You cannot simply double-click to apply it; it must be compiled into a CSM (Custom System Menu) file using a Windows tool like ThemeMii before it can be safely installed on the console. A common point of friction is the "brick risk": applying a theme from a different region (e.g., PAL vs. NTSC) can corrupt the Wii system files. Furthermore, because .MYM files often utilize ZIP compression internally, users looking to simply view the graphics can sometimes rename the extension to ZIP to extract the raw images without specialized software. For archiving or sharing, keeping the original .MYM is preferred, but for actual deployment, conversion to CSM is mandatory.
Convert.Guru analyzes your MYM file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MYM converter.
