I have some PSP and PS1 games I'd like to share that are missing from the database, here they are, using the format found in the wiki:

SLES-00845     Blaze & Blade - Eternal Quest   [E]

ULES-01513    3rd Birthday, The (Europe)
ULES-00267    Ys - The Ark of Napishtim (Europe)
ULES-01278    Prinny - Can I Really Be the Hero (Europe)
ULES-01521    Final Fantasy IV - Complete Collection (Europe)

As you can see, they are mostly PAL JRPGs. Not a lot of them, but I think they can be useful and I want to contribute with something.
