I've got this from the net

I see that you have a Xbox v 1.0 x-ecuter 2. For the PS2 get a REAL modchip....One it won't screw up your PS2 and two, you'll be able to play all of your backups with no hassle. It might cost more now but your be sorry later if you don't do it the right way. Believe me I've spent a lot of money before I figured out the "right way". You'll thank me later.

BTW, the fliptop is basically a hole cut in the top of your ps2 allowing you to swap the game without pulling the ps2 tray out. You won't be able to boot all games and you'll need to patch a lot. Take my advice on getting a REAL chip.
