No they will not
No, but PS1 games work with PS2.
NO ps2 games don't work in Ps1 only Ps1 games works on Ps2
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.
No, it doesn't I have tried it. But the stick you can use in PS2 U know that :)
they do your puting in the games that shouldn't work on ps2
no. because the graphics on the ps2 games are more advanced than the ps1 so the game wont work optimally
In order to play PS1 games on a PS2 you need to have a PS1 memory card in your PS2, so you can save your progress. Otherwise they don't work.
