One problem is that OPL is a lot less capable than OPN is, even 4 op mode of OPL3 isn't gonna help tremendously though with many channels available and made use of some impressive things can be done (a guy called MadBrain made some great things for example).

Another problem is that what is being done by Savaged Regime is not just good instruments, but also realtime parameters adjusting to create all the nice expressive sound that guy is able to do which means the entire soundtrack must be redone in such manner to even approach the nice sound possible.

Finding the instruments and tweaking them shouldn't be too hard but actually editing new things into the music data can be quite not trivial...

Are there any guides to just finding and tweaking the instruments I can look into to start with, then? Even if I don't know how to do something, I'm always open to learn. When I decided to make my mod in the first place, I had no idea what I was doing, but the human drive to learn can be amazing sometimes.

I imagine in many things the instruments should to follow the same ordering as chip registers (for ease of loading etc.) and they should stand out as on orderly and aligned table with many repeating values. This is assuming there's no compression etc. getting in the way too.

I wouldn't know about any guides etc, and all resources I know of are consoles centric.

That is something I've noticed regarding sound chips. The fan base for console chiptune trickery seems to be much larger than PC Sound Card variants. Thus information on such a topic is rather lacking in comaprison.
Still, thank you for getting me started on what to look for.
