This prototype by Ikzilion codenamed Dmix is a mini controller that combines a D-pad with DIY arcade buttons. It is quite slim, but there is a grip on the bottom left side. It seems best to place the controller on one’s lap for extra support until the grip is potentially improved.
The buttons are in the Noir layout. It seems that you can put graphics within them or even have them engraved. The secondary buttons are:
The seemingly detachable USB port can be found on the right side of the back panel. The printed circuit board (PCB) is by Brook. As for the color of the controller, it is expected to be flexible based on the customer’s request.
The Dmix is impressive despite being in the prototype phase. So, it would not be a surprise if the Dmix becomes a five star controller in its final stage upon launch!
