Just noticed that custom themes are STILL too loud, even at 20%. Might wanna go with 15%, instead. But in-game Superstar themes will still be too quiet by comparasion.
But hey, here's an alternate way to do it that will give you MUCH better results... but be warned.. it'll take a lot of work. However, I'm seriously thinking about it.
If you can somehow take the time to get MP3's of all 70+ superstars, and make EVERYONE a custom music in their entrance, then they'll all be the same volume, and then you can turn the slider in the game way down. But that'll still be a lot of work.
But if I see someone upload a file of every bit of music ripped from the game, i'll seriously think about doing this, to fix it once and for all.
Yeah, yeah, I know. What incredible lengths to go through. But this feature means that much to me. :p
