Replacement upper drive gear for the often now brittle or broken part in MegaCD mk1 units, (White cog), built to spec and should work as a direct replacement.
Version 2.0
Changes since v1:
Version 1 was tested and verified in Frosted Ultra Detail, though should work fine in the more expensive Frosted Extreme Detail for those wanting an even smoother result, Version 2's modifications should not affect printability of operability over Version 2 so you can order with confidence.
Works on:
Original Sony P/N: 2-625-188-02
Alternative Sony P/N: 2-626-907-11
