I saw a couple of earlier threads where user having same problem, but never saw any real solution. Just installed fliptop on my version 4 ps2, everything fits perfectly, but when you insert disc, it always spins off holder. The only way to get it to work is by taking white magnet disc off fliptop and putting directly on holder that disc snapped onto. Is there anything I can adjust so the fliptop will work as it is suppose to? I tried putting a folded piece of paper under white disk on fliptop hoping this would push the disk closer to the holder and make the contact required to hold disc in place when it is playing. Didn't work. Any help would be appricated.
