Converting GBA music to MIDI

Tell me please how to convert in-game OST to MIDI. I have gsf files from Turok Evolution but I can't open and edit or convert it. GBA2MIDI doesn't work.

IIRC, those converters work only with games that use Nintendo's "Sappy" audio driver... and if your game doesn't use it, you are basically SOL and you must transcribe the music to MIDI by hand.

Can you recommend any tracker to see the command list or notes stored in GSF? I tried to convert *.gsf to *.spqr (sorry, do you not know about Supreme Tracker Pro?), but I was failed.

Go ask in hcs64.com instead. There are only two programs that I know that deal with GBA music, and if it doesn't work with them don't even bother asking here. The programs in question are gbamusriperor VGMTrans, and I think they only support the Sappy sound driver anyway (Which is used in 90% of GBA games anyway).

Also, there is no guarantee that you can convert any "in game OST" to MIDI, especially if it's streamed or uses a different sound driver.

It's not possible because GSF files contain ARM program code and data used directly by the sound driver. If you don't have a program that understands the sound driver's specific format (as noted above).

I got an answer from SYSTEM (general admin of hcs64.com):

But I can not use Musyx on minigsf...

Then you have to get the ROM. Minigsf files usally only contain metadata and commands to play the song using the sound driver which is in the "big" gsf file. Hence the small file size, they're usually not bigger than 1kb.

Also I'm pretty sure they would tell you this as well.

I have got Turok Evolution. And SYSTEM also told me that VGMTrans is not possible for extract MIDIs or GSF from the game. But they don't know where I can get Musyx for GBA.
