Hi!
So I was playing FFVII and when I got to Nibelheim (not the flashback but when you return there in CD1) the battle music in the basement of the mansion was weirdly off, it's mainly a high pitch sound. I can't remember if this happens with original hardware or not. The basement music is different than in the rest of the mansion that for sure and seems fine.
I have searched in internet I mainly find gameplay of the remaster done for PC and consoles, where they might have corrected or changed that music.
Thanks!
