`%ROM_RAW%` - Replaced with the unescaped, absolute path to the selected ROM. If your emulator is picky about paths, you might want to use this instead of %ROM%, but enclosed in quotes.

`%ROM_DIR%` - Replaced with the dirname (except "/base.ext") of the selected ROM. Use this when you need to chdir to the directory where the ROM.

`%CFG_DIR%` - Replaced with the directory path of the EmulationStation configuration file contains (i.e. your .emulationstation directory).

`%INSTALL_DIR%` - Replaced with the directory path of the EmulationStation executable file contains.

See [SYSTEMS.md](SYSTEMS.md) for some live examples in EmulationStation.
