I've finally begun to produce the 5200 VX Controller in small quantities! As I produce, I will contact those who have privately messaged me in order of date of message so they can purchase the controller if they so desire. I hope to set up an online store when I've built up a sufficient backstock. I've tested the controller with my entire 34 game collection, and am yet to find a game that it is incompatible with (including Missile Command and Super Breakout). For those awaiting purchase of a controller, there are several things you should know; firstly, the controllers are 3D printed. This means they will not have the uniform, impeccable appearance that comes with mass produced products. Secondly, the controllers take a long time to make, and are being constructed during my free time; you should expect having to wait a while before receiving a controller. Lastly, they cost $150 each. I know this is a lot- more than expected or previously indicated- but I've invested a lot of time, money, and effort into making them a reality, and hope to pay for a bit of college tuition with them. Thank you for all of the feedback and support provided during years of off-and-on development. I believe this is the single best way to play Atari today.
