First, I should check if Mortal Kombat 9 was actually released on the PSP. From what I remember, the main Mortal Kombat 9 was for PlayStation 3, Xbox 360, and PC. There was also a version for mobile devices, maybe through PS Vita? Wait, the PSP is PlayStation Portable. I don't think there's an official port of MK9 for PSP. Maybe the user is referring to an unofficial port or a fan-made version?
