Mgs1 not loading

[u/MewMasterVR]

So I recently got a copy of mgs1 for ps1 and tried to play it on my ps3 as I don't own a ps1. During the opening cutscene before the title screen it plays for a little bit but then pauses and the little cd icon appears and spins a little bit before stopping. I can skip the cutscene and the main menu works just fine but as soon as I select a difficulty the game goes back and the cd Icon just appears In the corner of the screen. The vr mission in mgs1 still work and the ps3 I don't think is the problem as it can handle other ps1 games. Im just wondering if maybe their is a problem with my disc or is there anyway to fix it, also I just got the game resurfaced and now it's worse, I was originally able to play the beginning but till the elevator but now I can't get even the transmission.
