Hi there, saw your subject and thot I could piggy-back.
I recently bought a fully-mod PS2 (Messiah) which can play both NTSC and PAL Original and Copy games.
I am under impression that PS2 is backward compatible but my new PS2 can't play my Original PS games, even the original ones!? (tried Tekken 3)
Can anyone offer advice? I think I would take my PS2 back to shop but first see if any bro/sis have similar encounters?
