Your PlayStation is old, and chances are that the CD drive is defective.
no. because the graphics on the ps2 games are more advanced than the ps1 so the game wont work optimally
Yes (both PS1 and PS2) if you have the 60gb version. The 40 wont. Please note you can play PS1 games through your PS3, on your PSP (remote play) but not yet PS2 games.
The PS1 has 7,918 games bud
NO ps2 games don't work in Ps1 only Ps1 games works on Ps2
No, but PS1 games work with PS2.
With a emulator for the PS1
umm, obviously
games for a PS1 will work on a PS2 but will not be any better quality, and games for a PS2 will not work on a PS1 Yes. They can. But the graphics may not be as good on a PS2 as a PS1.
With a emulator program for the PS1
There are three GTA games on the PS1.
Yes, PS1 games are playable on all models of the PS3.
No. Since the ps3 is much more advanced then ps2, it wont be able to play it. Think of it like this. If you look at ps1, you cant play ps2 games there because ps2 games are too advanced to be played from ps1. Same applies for ps3 to ps2
