Here's a restoration mod for where's my perry. It does not require an external obb, which is already really good. It has everything unlocked. The only other things that were modified are the cutscenes. The cutscenes are fixed. None of the levels are modified and nothing else is changed. This is probably the best version to play on.

I did not create this, all of it was @campbellsonic
