Do any other games work? If they do, it's a problem with the game. If they don't, you might wanna get a new PS1 or PS2.

Try wiping the disks in a circular motion with a cotton t-shirt, tissue or cleaning cloth, then try again. If it still doesn't work, try a PS2 game. If it works, try another PS1 game. If the other PS1 game doesn't work, the PS1 part of your PS2 system may be broken. Your PS2 has, inside of it, a miniaturized PS1. If that mini-PS1 breaks, you can't play PS1 games. If the PS2 game doesn't work, you probably need a lens repair. If the other PS1 game works, then your games are defective and you should get new ones.

i think it is the bluray drive's lens.

do you have the emulator of ps1
I have 4 emulators for Pc

Your question is somewhat confusing, using a playstation 2 memory card, will have PS2 game saves on it, how would you play PS2 games on a PS1 from the save, you can't. If you just mean you are using a PS2 card for a PS1, the way a PS2 card saves data is different to a PS1 card, so it probably won't work You can use your PS1 memory cards in the PS2. You can only use the PS1 memory cards to save PS1 games that you are playing in your PS2. You can't save any PS2 game data to a PS1 memory card
