The Mini Game Sound Format (minigsf) is a specialized variant of the Portable Sound Format architecture developed by the emulation community for Game Boy Advance audio. It functions by storing sequence data while referencing external library files for shared instrument samples, allowing for highly efficient storage of game soundtracks. Although considered safe for general use, playback requires specific audio plugins or emulators capable of interpreting the hardware instructions contained within the container.
