Hi there, I'm not sure if this is the right place to be posting this, but it seems as good as any. I've just recently started using the OpenEmu and love it, but I've been having a problem using hacked ROM's from this site. It seems to run all types of games except for those with the extension .PFF. Has anyone else encountered this problem, or know that I'm doing something wrong? I'm certainly not very tech savy, and emulated games are completely new, so any help would be appreciated, thank you.
