I really can’t do it myself, just totally at the mercy of the kind and smart people in this community. But I’ll try to up this topic once in a while and be hopeful.
Thanks for your advice about the lightgun, I’ll surely check it out later for further improvements on the cabinet. I was also thinking about the Sinden gun but it’s bit expensive though.
About my setup, it’s an SFII cabinet with a Pi3 and pre-image. In general I only kept the 16-bit era (Capcom/SNES/Megadrive/NeoGeo) systems and only 15 games per system. PSX would be nice too but then this image makes use of Dragonrise controls which gives me a headache configuring wireless PS3 controllers.
I do have the original power switch working as it should by using How to Wire Stock Arcade1Up Power Switch to Inlet Module Switch Tutorial
Then the only thing that still bothers me is the volume switch…
…I could just move to a RetroPie system and all of my problems would be solved.
