I should mention my screen is Vertical...

That's probably the issue. I've never run Stella on a vertical setup, but the screen settings should be configurable.

@johnsorger6 I have used a spinner and joystick in Tron without any issues at all in AdvanceMAME. It sounds like you might have the analog control also mapped to your joystick LEFT which is a default mapping you would want to eliminate in the GUI menu by mapping controls for "this game".

@hamak Sweet! Thanks!
