vgm2mid is a command-line tool that reads VGM files and outputs Standard MIDI Files (SMF).

The .gsflib file is the crucial counterpart to the .minigsf file. It is a comprehensive library that holds all the shared data for a game's soundtrack, such as the instrument samples (SoundFonts), sequencing data, and the music engine itself. For a set of .minigsf files to be playable, they must be accompanied by their corresponding .gsflib file in the same folder. Without it, the .minigsf files are just empty shells. The .minigsf files are typically quite small, often just a few kilobytes in size, while the .gsflib file can be much larger. minigsf to midi
: Specifically designed for games using the standard "Sappy" sound engine. It can take a GBA ROM as input and output MIDI files and a soundfont automatically.
VGMTrans will scan the file and list the instruments, samples, and sequence tracks. Look for files labeled SEQ .
file is typically very small (~1kb) because it only holds instructions for a specific track. It depends on a much larger If VGMTrans fails to recognize your ROM, try:

Do you have a specific MiniGSF file that refuses to convert? Check the VGMTrans GitHub Issues page or forums like SMW Central and Zophar’s Domain for game-specific sound driver patches. For a set of
Converting .minigsf to MIDI is a specialized process, as GSF files are not typical audio files, but rather sets of instructions for the GBA’s sound driver. This article provides a comprehensive guide to understanding and achieving this conversion. What are GSF and MiniGSF Files?
You successfully extracted the notes, but not the instrument bank mapping. Fix: This is normal. You need to open the MIDI in a DAW and manually assign General MIDI instruments. Look up the original GBA game’s sound track list to see what each channel should be (e.g., Channel 3 = Bass, Channel 5 = Lead Square Wave).
Converting MiniGSF to MIDI opens retro game music to modern composition and remixing while preserving its structure. With a decoder, event-to-MIDI mapping, careful timing conversion, and instrument design, you can create editable MIDI files that capture the original melodies and make them playable in today’s tools.
This method does not always capture the sample instrument name. You will get the notes, but the "brass" might appear as a generic piano. You will need to reassign SoundFonts later.
If technical extraction fails, users often turn to AI-driven audio-to-MIDI tools. While not perfect for multi-layered tracks, they can help reconstruct melodies:
