Scroll a bit to the side and you'll find some file names. At least that was the case for me.Same here, but unfortunately I haven't been able to find any sort of program or any tutorials whatsoever :-(
Btw what program did u use to open the inf file? Cuz I tried Notepad/Notepad++ and it only displays gibberish.
I used this tool to extract GT4.VOL http://gtr.ajb-tech.co.uk/files/GT4FS.zipI doubt there are any but any updates so far? I've even tried using the GTSeq2Mid file on Github but that only recognises .seq files from GT1, 2 and 3, and just found out the seq file in GT4.VOL is the same as the one in GT3 (because of GT4 Prologue using GT3 music)
So far, GT4's instruments are easy to rip using PSound. The main issue is playback or sequence files.Ins files have the instruments, the other ones have the "partition". The format hasn't been cracked as far as i'm aware on the RE side of things, though i know that someone was able to somewhat convert GT2 midi tracks to actual midi. It's a slightly different (probably simpler) format however: .seq
The seq/vab format is PS1. The PS2 uses formats called .hd and .sq.Ins files have the instruments, the other ones have the "partition".
