PS1 to PS2 cd baackups

If the copy game is playable then as you have said it may be Japanes, then it would be NTSC. The worst that can happen then is that the game may play in B/W. To overcome this, look up the game in megagames.com to find an NTSC-PAL patch and copy the game to hard disk patch the game as per tutorials at megagames; burn the game back to CD. Or else buy a NTSC to PAL convertor box.
