I recently won a Space Riders pin at an auction. The main problem I noticed was a blown transistor on the auxiliary board.
My main board is labelled A006020-15, so it is from a Middle Earth (ya... it's also got "ME" written on it...which should've been the obvious giveaway). Reviewing reference photos on pinwiki, there don't appear to be any obvious differences aside from ME having three (3) transistors at J8 where Space Riders has five (5).
Can this board be used for Space Riders with the correct ROMs installed? If not, are there modifications that can be done to make it work?
