Not sure if I exactly understand what you are saying, but I think you want to go PS2->VGA. There are several "VGA Box" type devices out there. I don't have experience with any of them but have been thinking about putting a PS2, XBOX, or GC in my VGA cabinet too. Let me know how it works out for you. I think most of them can only do 640x480.
