Can you play ps1 games on a ps2?

PS2 can read PS1...depends on games likes Xbox and Xbox 360.

Yes :)

You can play PS1 games on a PS2 since the PS2 has in build hardware to support it. BUT important to note! Memory Cards... the PS2 memory card uses another method of storage then the PS1. PS1 games can't detect or open PS2 memory cards.

So you need a PS1 memory card. Even worse.. if it is PS2 slim you need to ensure that it is a first or second party memory card. Some 3rd party memory cards are not recognized!

So yes you can and many do..ah the times playing the original Gran Turismo's.. Final Fantasy's Grandias..

A pro tip: Official PS1 memory cards store very little.. BUT you can use a PS2 memory card to backup the PS1 saves. So you can start the PS2 in the menu without a game disc and move safe files between PS1 and PS2 memory cards. A very good way to keep backups.

Ps1 Croc

Ps1 Spyro

Yep, I used to own a ps1 now i own a ps2 and i can play all my old games on it just fine. but you cant play ps2 games on a ps1. and im oldschool but croc and spyro are amazing games hahaha. I didn't like the riptos rage too much though. :) good luck, hope I was helpful!

Actually yes you can play ps1 games on ps2. i am not sure for all the games but all the ps1 games i had worked on my ps2.

It says "ps2 is not backward compatible with ps1 games."
