(Somebody said:) ebay
Ebay is best, but amazon is almost as good.
PlayStation store will sell or give downloads of some PS1 games for the PS3
You can find them at the Playstation Store and at sites like Ebay and Amazon
yes, usually used. Actually this must be an old answer because it is getting hard to find new PS2 games let alone PS1 and never new
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.
From what I can see they only carry PSP, PS2, & PS3 PlayStation games. I could not get any PS1 games to come up on a Gamestop search. (see related link) Amazon.com still has a number of PlayStation games for sale( see related links)
