So, I just dumped a copy of Carnival Games: Monkey See Monkey Do.

The checksum just so happens to match

So, what do I do now? The games have different titles in different regions, despite the disc being identical.

usually thats when you put the alt title in non-latin field so it's searchable
imo USA release should get priority since Europe could have regional names for every area its released in
