FF9 won't work properly. It might be freezing but idk?

It's my goal to play through this game this summer but some unknown force has picked up the role of the antagonist. My original copy which sat around collecting dust of a couple years isn't working. So i borrowed my friends copy which looks like its in mint condition. Now, my problem is that when I'm playing as Vivi and i promise to be the rat kids slave he asks me to go down on him. I just cant tap x fast enough to satisfy him... jk that's an example of my lame humor. Now its when I go to the enter the bell tower to sneak into the play it goes to a black loading screen and then nothing. The music continues to play but the game stays at a black screen. I've tried washing the disk and cleaning the lens with a lens cleaner. Even pulling out my old PS1 but nothing works. Any advice?
