Linux and Mac are both UNIX-based, and by default use case-sensitive filesystems. This means you can have a file named Pam.xnb and a file named pam.xnb in the same directory/folder. What this means is that in order to override the original files which the game is using, the new files need to have the exact same characters, case and all. The list I gave are the files that need to be changed to those characters, just adding those capitol characters here and there. I've already fixed it and have attached the fixed version for you here. I just downloaded this today so it should match the current version in every other way. Yeah, it's an easy fix! ^n.n^ Oh there are other fixes still to roll into the main version? Well, if it helps, here is the case-sensitive fix from me at least!
