I could find that I'm not the first person to try ripping Disgaea DS's music sequence stuff, but I couldn't find what exactly you're supposed to do with this bgm.dat to actually get a sdat/sseq/midi/something usable out of it?
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
