First, this is my first post here, so I don't know if there is a specific method to post issue. And yes, I read the troubleshooting guide.
It seems european version of TimeSplitters Future Perfect has a wrong entry in the database while scanning my folder. Tree is actually like this if it can help :
F:\RETROARCH-WIN64\GAMES\PLAYSTATION 2
TimeSplitters - Future Perfect (Europe) (En,Fr,De,Es,It).iso
My game was named TimeSplitters - Future Perfect (Europe) (En,Fr,De,Es,It) (Beta) after folder scan, but I'm almost sure this is not the beta version, unless my provider was wrong, but I sincerely doubt that.
