hi this is my first time to post a message in this forum. I read the rules not to post questions that were asked but if I did sorry for the inconvinience. My question is that I have a US PS2 and I have spent hours to find what version it is. Some sites says it is 7 and some says it is 4. but I have an 8 screw and the number SCPH-39001. I just brought a flip-top and it is coming and I just saw some of the messages saying that version 6 or above wouldn't work with flip top and back ups with DVD rip(don't know the difference between dvd r) or dvd r. Can someone help me identify the version of my PS2 and how version 6 or above effect the flip-top. can it play my back up games?
