SEL

SEL files are a type of symbol table used by Wii software. They are required in order for a game to link to RSO files.

These files contain symbol names and mappings for any function required by the RSO files that the games link to, however in some cases the SEL file contains all functions available in the game.

Megazig's WiiTools contains an IDA loader plugin as well as a Python script to parse these files.

Notable Uses

  • Wii System Menu (versions 3.4 and below include all(?) function definitions, versions afterwards appear to be more conservative)
