GBA Sound Format

From Wikipedia, the free encyclopedia

GSF is an emulated Game Boy Advance audio format based on Neill Corlett's PSF (Portable Sound Format), developed by Caitsith2 and Zoopd. GSF files appear as either .minigsf or .gsf, mostly being of the former. The .gsflib must be extracted into the same directory as the .minigsf files.

These emulated audio files can be played on the Windows platform using Nullsoft's Winamp and the Highly Advanced plugin. Mac OS X users can play them using Audio Overload v2.0b7 or later. Linux users can use PlayGSF, or the port of Highly Advanced to Audacious.

The players convert the files internally into a Game Boy Advance ROM that is then run through a cut down emulator with no support for graphics hardware. Even without support for graphics, though, emulation of the Game Boy Advance can be quite processor intensive, and neither program works well on machines under 500 MHz.
