Retropie..Intellivision controllers with other emulated systems

[Duglor]

Hello.

I have the ultimate intellivision flashback retropie currently. I can of course plat the intellivision games beautifully. I can also play atari and colecovision games using these controllers, though there are flaws. I can load up tg16/pce games and msx games, but they do not work with the intellivision controllers. Is there a cfg file or some simple files I can download to my pc, put them on a usb, and get them into the retropie that would let me play atari2600, msx ,tg16' colecovision, and the turbo colecovision game with the intellivision controllers and run well? I have the 2.6 currently. I have been researching for a week, but have failed.
