I talked to the guys over at X-Arcade and requested a hybrid of a dual xarcade w/ a trackball fitted and they said no problem. They ran a very limited quantity of the prototypes. I have the first one available to the public so I figure I would do a review on it. I must apologize in advance for the pictures my camera is broken. These were taken from a old digital camera . Here's some pics of mine.

Heres a pic of the side of the controller

As you can see this controller is pretty! It is made of mdf and a poly laminate. Its got a textured feel to the black laminate or veneer. and is fully t- trimmed so it can take some bumps without taking damage to the mdf. The keyboard plugs into the back and the plug from the controller plugs into your PC keyboard slot. This gives you use of keyboard and joystick. Also the trackball has a cord that plugs into your PC mouse slot and this gives full mouse capability to your trackball. Theres a new feature called tracklock that also works into this configuration.

The trackball is of good quality and was accurate with every game I threw at it including several golf and bowling games. Wow did we have some fun tonight! It worked very well in every game and even selecting the games we wanted to play using a new feature called Tracklock. There is a green lighted button on the top right side of the controller that when pushed on activates the center row of buttons to act as mouse buttons one, two, and three. When pushed in the off position its no longer lit and your buttons go back to normal. Wether on or off the trackball is always one. Another new feature used is called horizontal disabler. There is a button in the rear of the controller where the cords are and programming button and switches are. Hold this button in and it disables the trackball from steering left or right. This great to cheat or get real straight shots using the trackball. I for one liked this feature but only used it to anger a few friends. I couldn't hold back for long and let the cat out of the bag. This trackball will work for consoles that can use a mouse and only with games that can use a mouse

Lets move on to the dual joysticks. I felt the joysticks and buttons worked and felt great. It took on every fighting game imaginable no problems hands down. The sticks and buttons were fast and responsive and pre configured using Mame32fx and Mame32plus. The only game I found not configured right was mortal kombats series. No problem though buttons can be reconfigured easily thru Mame.
Pros: Very fast and responsive
Works right out of the box with Mame32 plus or fx.2
Controller works for consoles
trackball works great and new features
Tracklock is a must have and horizontal disabler is nice too.
Is a great stand alone controller.
Cons: Trackball only works with mouse compatible systems and games
Config file for some games needs to be fixed.
Because of pinball buttons and buttons in the back of controller
makes it a chore to mount on a arcade cabinet.
