How to rip GBA instruments?

[Pingus!]

I've been wanting to do this for a long time, and I've searched for tutorials time and time again, but haven't found anything useful. So, does anyone here know how to rip GBA instruments? Basically, what programs do I need?

Thanks to anyone in advance.

Hey bud! There's a great program out there called gba mus ripper, which you can pick up here:

When you load the GBA rom in, it locates the sappy engine some games uses and splits the *.mid files out. You just need a program that can play *.sf2 files with midis. I usually use synth font as you can re-export to wav, with the soundfont applied.
