Anyone have a CX-22 and want a Missile Command trakball hack cart?

[Bucket Brigadier]

When I first got MCTB I had a similar problems due to a mis-labeled Trakball. I had a CX-22 internally which externally was built like a CX-80 and was labeled as such. My MCTB cart wasn't working, and I was baffled as it was labeled For use with CX-80. Eventually, with some help, I got it figured out and got a CX-22 version of the game for my CX-22 in disguise. Game's worked fine ever since; I like it a lot better than the original Missile Command on the Joystick or the TrakBall in Joystick mode; score a lot higher and the gameplay is a lot better in my opinion.
