Item description:

Rips sappy GBA audio and displays location of files within the game.

Playback is capable in Atrius' adobe AIR program GBA Jukebox

From the readme
To use simply drag & drop a single gba rom file onto the executable.
The audio data from the rom will be dumped to "output.gbas", if the
file already exists it will be overwritten.

NOTE: When audio data is dumped in this way a 16 byte header is added
to make the file compatible with my (Atrius') GBAjukebox program.

If you drag & drop 2 files onto the executable, the audio data from
the first will be dumped to the end of the second file.
