So in difference to my LISY MPUs which do use software emulation, my FPGA MPUs use hardware emulation.
At the moment I do have:
-> BallyFA for Bally pinball machines
-> GottFA80 for Gottlieb System80/80A/80B pinball machines
-> GottFA80_PLuS for Gottlieb System80/80A pinball machines with integrated Power Supply & Solenoid/Lampdriver
-> GottFA1 for Gottlieb System1 pinball machines
-> GottFA1_PLuS for Gottlieb System1 pinball machines with integrated Power Supply & Solenoid/Lampdriver
-> WillFA7 replacement of a Williams MPU (System3 up to System7) including the driver board!
Note: you can check if your FPGA is working by using my FPGA checker!
