So I got Ricardo‘s Jammix Mister in an ITX-case like a month ago and wired it to my Taito Egret 3 cab. I prefer playing every action game with an arcade control panel on a sturdy cab, even all the console stuff.
Super happy with the results, but I should’ve placed an order for the item without the case, as it obstructed the JAMMA interface. The import fee was outrageous, almost € 100.—. Guess I should’ve asked Ricardo to declare a lower value for customs beforehand.
The only issue I’ve had with the Jammix device, was not getting a picture at all, unless I connect my tri-sync monitor’s separate VGA-cable directly to the MiSTer. So JAMMA is properly connected for controls, but I’m also using the MiSTer’s analogue-out to the cab’s VGA-in at the same time. Works like a charm.
A friend of mine had Antonio Villena’s USB-JAMMA adapter, but wasn’t getting a picture either. Unlike my Egret, his Astro doesn’t have a separate VGA-cable to circumvent the issue. He now has a MiSTercade, which he got to work, picture and all, with only the JAMMA interface.
I assume Ricardo could’ve pointed me in the right direction, to get his Jammix displaying a picture without also relying on the MiSTer’s analogue video-out port, but in my use case, it’s simply not needed.
I still have Antonio’s USB-JAMMA adapter and that one kinda did a decent job, but shaving a couple more milliseconds of lag off with Ricardo’s Jammix is the real deal. Now it feels like I’m given a full 2 seconds more reaction time when playing any game on the MiSTer, although it’s obviously much less.
Pretty sure I’m not imagining things either, due to a placebo effect or some such, cause I can actually beat more games now.
What matters is that gameplay seems exactly the same as I remember it from the arcades. Lifelong goal achieved 
Seastalker, you can get the full fat console experience with the Jammix MiSTer, whenever you fancy removing it from your cab. Personally, I’d just never do that
