LOL!!!
I'm in NTSC land,
which my location state's U.S.A.
I don't think that makes a diff. seeing as the BreakerPro disc has a setting to choose between PAL & NTSC, at least mine does.
Are the versions you are trying to play NTSC ?
Anywho, i use DVD Decrypter (to both burn and rip) Cdrwin, CloneCD, heck, i've even used nero to burn back images and never really had any problem backing up PS1 game.
I know CloneCD will allow you to burn at 1X, 2X, 4X, 6X, ect.
I saw someone here saying how that is a bad program for diff. reasons, but i've never had a problem with it....
And i just use standard Verbatim 80min 700mb cdr's.
And i use a slim PS2 & my son uses a fat ps2.
