Cool. No problems with Towering Inferno now. Thanks, cvga. I never would have thought to use the "wrong" joystick. Decent gameplay and kind of fun...now that I can move around.
And...Starmaster also works. So, thanks to Tony The 2600 for that tip. Looks like this one is a little more complicated than I gave it credit for. Not a turn on and play type of game. Time to study that manual.
Yep, I give them a good cleaning as soon as I get them, especially from flea markets. Usually the ones ordered from more reputable sites seem to be ready to go out of the envelope.
Such odd gameplay for both of these, or ways to go at playing them. Thanks for the tips, y'allz...
