charlie u said that you need the orginal modchip and the origa chip to play original dvd's? what is the original modchip?
ANSWER: Bearing in mind that I have the JAP SCPH 15000, the "original" modchip was the modchip.com Utility Disk Beta. I posted the DVD-R boot method for this about a month ago. The v1.25 OrigaChip does play DVDRs I believe (check the Origachip web site please).

Is there anything else i should no about the ORIGACHIP be4 purchassing it?
ANSWER: Check the version you order against its published functionality on the OrigChip website. It boots import originals directly and backups via a swap trick.

ANSWER: Yes - there are three versions (US/PAL/JAP). A future release (now in development suspension I understand) is a single configurable chassis. What is your PS2 - Remind me?
