Well whatya know, it worked. I would have never thought to look in a different .prs file to find, you know, .50cal sounds. You'd think .50cal sounds would be under .50cals, but that would make sense. We can't have any of that.
Sounds are working great now, I cranked up the spl levels from 115 or 120 to 165, and the .50cals on every fighter I've tested are much better.
Thanks for the help!
