Machine Gun

Post by Arcade-Projects »

Hi! I'd like to show this awesome device... its' called Machine Gun. I want it to be a simple, safe and cost-effective way to connect JAMMA boards to SCART TVs and audio amplifiers or speakers, with a focus on audio and video quality and electrical correctness.
