I got my Ironclad Plus today. Got it set up and working. So far, it's awesome!
Here it is mostly hooked into my case
And done
Since I have it in a cab, I turned on arcade mode by hitting the config button 7 times. You gotta do this
very fast. I didn't think it was working, but after trying it many times, I realized very fast was the ticket (all seven clicks in under say a second or two). Now whenever my cab comes on, the MiSTer comes on automatically.
I have two cabs, so got two of these things.
So far, really dig it.
