Mii Database Editor

A Java GUI application for editing Wii's Mii database

The Mii database (RFL_DB.dat) can be found at /shared2/menu/FaceLib/RFL_DB.dat

Capabilities:

• Load/Save Mii database files.
• Automatically calculate valid checksums when saving, allowing files to be opened in the Mii Channel.
• Fix Mii databases with inncorrect checksums.
• View raw Mii data.
• Import/Export individual Miis.
• Change System IDs of Miis (Miis from other Wiis cannot be edited on the Mii Channel).
• Rearrange Mii data in the database (this does not affect functionality in the Mii Channel).
• Render Miis directly within the app.

What it does NOT do:

• Edit Miis. Use these tools instead:
  • Mii Channel
  • Mii Info Editor
  • My Avatar Editor
• Convert Miis to different consoles (Wii U, 3DS, Switch).

Future Plans:

• Mii Parade support (View/Edit/Save Mii Parade data)
• Modify Mii IDs (Miis with the same Mii ID can break certain games)
