That is interesting. I have never moved a game from High to Low or visa versa but I understand why someone might.
I am guilty of buying stronger flipper coils for an em which amounts to the same thing.
Similar; I usually install a jumper on the EOS on the credit unit. It has a male / female staycon in it. All of my games are coin op but if I sell it, the new owner can easily switch it one way or the other without "bending" the switch.
