ps2 compatibility
 

Hi,just wanted to know if anyone knows if you can play the back up copies(cd-r) from the ps1 and use them on the new ps2 ?

thanks

Yes - subject to a Modchip being installed and the boot rules for that modchip being observed. For example, with my modchip on a Jap PS2, I have boot with a Jap PS1 original and swap the PAL PS1 backup in at the appropriate time. A PAL PS2 will require a PAl PS1 original for booting.
