I have a slim PS2 77001. I've been having a lot of trouble booting up the SwapMagic 3.6 DVD that I just bought. Most of the time, the disc can't be read. The times it CAN be read, the "Playstation 2" logo that flashes is distorted and the screen just fades to black and gets stuck there. I've made sure that the DVD is placed in the spindle properly and resetting doesn't help.
However, the CD version works without a hitch. It's only the DVD.
I've cleaned the lens and DVD itself but the problem is still there. I don't think it's a lens issue anyway-- I can play original games fine and the CD is readable.
I have the same issues with my SM dvd. When it sticks on the black screen I open the flip top and touch the disc while it's spinning, near the lens, and it starts right up for me. I do not know if this can damage the ps2 or sm disc so try at your own risk. Good luck.
