Hello again! I'm making another game while I'm on vacation, but what I want to be able to do is have it use external level packs. Hopefully, I can open a menu in the game, and every valid level pack on the calculator shows up. Problem is, I have no idea how to do this. My idea is to have every valid level pack start with some 8-byte signature at the beginning to validate it, but how would I search every appvar on the calculator for this?
