Hey, i know i have posted a lot the past few days about problems i am having with a few duo2 chip installs. I would first like to say thanks to everyone who has helped me out.. i am a noob in the Ps2 modding scene and everyone here has been so helpfull with my problems. Now on to my next problem. I have a duo2 chip on a V7 ps2. I think i installed the chip right as there are now no problems with playing origional PS2 games. But i cant get backups to work that work on my v9 ps2. the V7 has the "crappy" 400c laser on it and it is a used one. When i put the backup in and do the reset hold untel the blue light comes on the cd-drives sounds like it is trying to read it then i get the error message in the red background saying "please insert a playstation or playstation2 format disk". I dont have a DVD burner and the dvd backup i have wont play in it either (but it wont play in another ps2 i have). Could this be the laser or what? Is there a way to test the dou2 chip to see if it is functing without media? or do i need to try other media untel i get something to work? any advice on cd-r or cd-rw media to use?
thanks for your time and help
