I hope this information will help. I pulled a Sally chip from my old 4 port 5200 and installed in my early 7800 with expansion port. Alien brigade work perfectly now. Not sure what a difference it made, but works perfectly now.

Interesting, is that on the early or a late models? I have early AT85 with expansion port.

Thanks, I thought it was on my end. I hope Fred will get a chance to look at it some time.

Is it possible to play Alien Brigade yet? I tried all version including from Trebors Propack.

I would like one for my Atari 5200 please.
