I just bought an area 51 machine, and i have been reading that there is a way that you can add maximum force to make it a duo but read that i need a duo board or something. I took a picture of it and im wondering if anyone could tell me if it would be compatible with the kit that you buy to add maximum force. Also I was wondering how hard it is to change a board to a different shooting game that is compatible with the JAMMA arcades. Would it be as simple as buying the new board and installing the rom onto the hardrive then hooking it all up again? Thank you for your help in advance.
