Hi - I have a PE+ with Superboard. Everything works fine running a Multi-Poker chipset. I was thinking of converting my machine by gutting the CPU, replacing the CRT with LCD and putting in a Rasberry Pi running MAME on Retropie. I still want the coin acceptor, bill acceptor and hopper to work. I know J Stolis helped write the MAME driver. Does anyone know if it's possible to send and receive the pulses to those devices. Handling the actual buttons seems easy using a USB decoder. I was also wondering if I could add a printer - but don't think the printer driver was written in MAME. Any thoughts?
