Does anybody have something I could test my mod-chip with? Its a DUO3 Gold and I want to see if it's my burner (I'm using Taiyo-Yuden DVD+Rs) or my chip that is causing the DVDs to not boot. The first disk I burned went right to the invalid disk screen, the second one I burned is stuck on a black screen. I think the chip is working; the PS2 stills plays games fine and I am able to disable it (get the DISABLE message when I hold start during bootup). Any ideas?
