I apologize for not understanding clearly. No offense intended. It seems all the emulators need to update for this, tried in Citron, Eden and Ryu 1403.
I think Eden is the only emu thats active, I'll send a note there way.
I was able to get custom music in using your mod loader, however, the tracks cut short. I am assuming because looping info is still coming from unmodified bgm.bnk?
Can I use your earlier method in conjunction with the loader to alter song length data?
