Extract text from Wii themes (MYM)
To convert MYM themes to another format, you need MyMenuify or other System software.
To convert other file formats to the "Wii Homebrew Theme File" file type, you need software like MyMenuify or a similar tool.
The .MYM file extension is primarily a custom system menu theme file used by the Nintendo Wii homebrew community. It contains modified graphical assets designed to replace the default dashboard interface of the console.
These files are typically managed and applied using the homebrew application MyMenuify, originally created by developers Scooby74029 and IceFire. To build or edit these themes on a computer, users rely on desktop tools like ThemeMii.
Users often need to convert or open .MYM files to edit the custom background images or icons inside. The primary disadvantage of the format is that it is highly specialized and completely useless outside of a modified Wii console or an emulator like Dolphin. It is an undocumented, community-created format that most operating systems will not recognize by default.
The best workaround is to treat the file as an archive. Because 78% of .MYM files are internally structured as standard ZIP containers, converting or renaming them to ZIP allows users to extract the embedded TGA or PNG image files without losing quality.
This file format is notoriously difficult for standard software to handle because it was developed strictly for proprietary console hardware modifications. Standard online converters fail to process it. However, you can just drag and drop your file onto convert.guru to identify the format, view it, and convert it when possible. Our analysis tools detect the underlying ZIP structure, allowing you to extract the enclosed assets effortlessly.
Convert.Guru analyzes your MYM file, detects the exact format, and lets you read the text inside.
Users also converted CSM, ZIP, RVZ, AZX, MSCZ and A3 files.
If you want to convert MYM file to CSM, you can use MyMenuify or similar software from the "Console System Menu Customization" category. In the File menu, look for Save As… or Export….

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.
