Actually you might want to avoid trying to use this with Bootleg. I used Bootleg with it and for some reason this screwed up the mod sidequsts near the end of the game. The guy who made the mod fixed the problem through some trial and error but you can completely avoid the problem by not using Bootleg.

Maybe just try to use FF7Music. A lot of the mods in Bootleg don't work anyway because creator of NT has an installer that will just overwrite everything.

I'll try to upload a couple video demonstrations of the mod later today. They're not very good - my comp can only handle like 13FPS whenrecording with Fraps but you don't have to watch the whole thing. Just want to give an idea.

Also, if you looked up some videos of this online, the videos on YT are all outdated. They're from the last version of this mod. There's now a Level 70 cap and no HP Plus materia. This is because he's working on a New Game + feature. Anyway, bosses in the version I played are substantially different from the ones in the videos currently on YT.
