psx help

I got my PS emulator to work last night. i played for about an hour. Now this morning when i try it i see the "loading" page then it turns black and the music starts skipping, kind of repeating itself in short amounts of time. any ideas as to what i should do?

the game is Final Fantasy 7, there is only one glitch in the game when on my box. When there is supposed to be a hand in the battle view it shows up as the enemies feet. but i want to get it working before i fix this problem

 

i odnt know if i have the bios in there, i never downloaded it but it did work once

 

i just checked and it is in there but ff7 wont load anymore and i followed the instructions on how to make an img file using Alcohol 120%

 

i deleted every finalfantsy save in my save directory. it now works fine. but i lost my game data. does anyone know hwo to fix this?

 

bump, i really need some help

 

ok i got it to work fine. now i need help. i am playing final fantasy 7 and i am now on the second disk. at the end of the disk when it says please insert disk 2, i go to load new cd image. i click on disk 2 and it tells me "TOC error - aborting" what do i need to do to fix this? when i load the disk like i do disk one it works fine
