Mr. PSX and PS1 Final Doom w/ PS1 Mouse (1080p)

So. Mr. PSX made some finds - that is, Final Doom for Sony PlayStation. And finally another game to play with the PlayStation Mouse I've had a while now. Dunno if I use it to me playthrough, but yet to play another game with it though. I've emulated this game through before (PAL version), it was semi-miserable (due to emulator). But here, should be good. ‪@ClassicDOOM‬ is probably a resource of usefulness with it again... Game: Final Doom (SLES-00487)
