After I installed the planet ring, I had adjustments to make with the crane, the inlet ramp guide ( I had to bend it a little so the balls wouldn't fall off) and the ring itself so that it would line up perfect . I then played it this way for a few days, and when I was satisfied with the results (no dropped balls and the crane picking up every time), I then installed the rom, and it has worked perfect every time.
With the mod the optos must sense one ball in for every ball out of the planet or nothing works right.
