Hi,

 

Anybody ever have an issue where their AtariMax CV Ultimate SD Cart menu scrolls endlessly and doesn't allow button press selection in one console but not in another. If you stick in a standard cart it plays fine. The Ultimate Cart works perfectly in my other console.  I've cleaned the cart edge and Cart edge interface with IPA and swapped out controllers in case the UC is just picky. Any ideas? Thanks!

 

So, 1 hour later: 

I found with the Cosmic Avenger cartridge, that with no controller in one or the other port, player 1 goes straight down into the ground with no controller while player 2 flies straight with no controller. Funny that it works right with a controller in the player 1 port. Although I notice some temporary player 1 graphical artifacts that go away with player two and then don't come back with player one. Controller I/O chip or just a 9-pin connector?

Sounds like one or both of the controller port IC chips on the motherboard are bad and need to be replaced. They will need to be desoldered, a socket put in place and then new IC chip(s) placed into the socket(s).

Yes, controller ICs.  Console5.com sells a repair kit.

Okay, sounds like a good place to start.  Thanks guys! And it's nice to know it is still easy to get the main repair parts for these relatively cheap. I see they have a decent Wiki, too!
