GSLIB is a specific audio library format derived from the Portable Sound Format architecture, developed by the emulation community for Game Boy Advance audio. These files store shared sample data and driver code referenced by MiniGSF files, allowing multiple ripped music tracks to remain small and efficient. Primarily used within specialized audio players and emulators, the format poses minimal security risk as it strictly contains binary audio data and instructions for hardware synthesis.

}
Go
