Hi.
I have the Ultrastik 360 but, as many others, sometimes I missed the "precision" of switches and other small things...
Well, I modded it adding the switchwes... it's a really simple thing to do, simply insert the standard ones.
Of course, I added a controller (using an arduino leonardo/micro) and now my system see, with a single joystick, dual controllers.
The first is th ultimark one in analog mode (useful for analog controls and games like qbert, tron, etc...) and a leonardo one, with digital directions.
In addition, the frout mounted restrictor, in 4-way mode, works perfectly with digital switches too!!!
Now I am happy :-) and I would like to spread this to other people who, maybe, can find this useful.
