I was looking a their multi-game cartridge for Amstrad GX4000 and was about to place an order before I realized the dude behind retroelectronik.com "could be" the guy who stole the design from JNX for autofire jamma adapter.
Can someone confirm?
I have one of his superguns...bought it since it was cheap and wanted to test it. Hadn't given me any issues so far. Not vouching for it, and the power delivery over video needs to be remedied before jacking it into a framemeister (TTL vs 750ohm) but its decent.
I need to get a nicer sueprgun though eventually. I've acquired some rarer pcb's that I don't want to mess around with
