Open VGM files in editor
Post Posted: Mon Sep 09, 2019 8:24 am
Hi!

Im new to the world of VGM music. I havent really understood from the information ive googled if its possible to open VGM files for editing/studying. Or is it only possible to play them?

They are a binary format. You can convert to text using VGMTool to see the data but it's not editable or informative.

Spend some time fiddling with Mod2psg2, it's a very good tracker.

Editing and playing in low speed makes possible to study melodies of all games, and you can also begin making your own.

I waited for a few days but now I have to wonder, how much interest would there be for a pure vgm editor? I have a few ideas on how I could make one, and I'm often bored enough so I could actually do that, but first I want to know how useful it would be. Not very much, I guess.

Well, I’ve hand edited VGM files a handful of times and managed OK with a hex editor - but then I ought to, it’s sort of my format. I don’t think you could usefully make any music this way.

you can actually convert the binary vgm files into hexdumps and edit them as text, and then convert bath them to vgm files back again

what i used to do was editing these hexdumps in an ide like geany, and in the same directory having a makefile that calls a bash script that converts it back to a binary vgm and plays it, this might help on the iteration process as you just need to press shift+f9 there

but when editing vgm files this way you are actually editing registers and their values, and time delay values between them, which might be not as "comfortable" as using a tracker or pianoroll interface
