Fully tested in mint, like-new, condition. Please see all the pictures for details. Keep in mind that all PS1 games can also be played on all PS3 units. Not just the 1st generation, but all of them. 
This game came from the original owner who bought it back in the 1990s. It comes with the original receipt of purchase, along with a cheat code sheet he printed out for it. As a collector myself, it breaks my heart to say that he passed away recently, and it's the only reason why these games are available for sale. So, out of respect, this game must go to another collector that will love and cherish it. May he rest in peace.
