Thanks for the kind words and support. It means a lot to me.
Minigun is completely safe to use with an OSSC, both audio and video. This was a mandatory design requirement, as was / is safety in general.
I'm aware of the DB15 spacing issue with Undamned encoders. It is a shame, just couldn't space them any further apart due to the compactness of the PCB and other surrounding components. A couple of rough ideas spring to mind for future revisions... I could remove the 3.5mm audio jack which would allow for more spacing between the DB15s. Alternatively, and perhaps not as elegant, I could fabricate a separate PCB with female DB15s on one end, designed to dock into the DB15s of the Minigun, and on the opposing end have 2 x further spaced female DB15s for controllers to connect to. I guess the advantage here is it's compatible with the current editions of the Minigun and also one could add a few extra controller ports, say for Saturn / Genesis / Snes etc.
