For Christmas, I received a rather nice set of Atari stuff: 26ish 2600 games, all in box and most with manuals, and 4 7800 games all in box with manuals.
I also got a huge set of various controller-type peripherals: two of the Gemini things, two of the 7800 joysticks, 3 2600 joysticks and... a trak ball?
I plugged the TrakBall into my 7800, thinking it was for Centiped/Millipede (though I could be wrong-- this stuff is before my time), and the ship just veered right and stayed there. I'm not sure if there's a special setting for it or something, or if it's 7800-incompatible, or what, but it does weird stuff. However, spinning the ball makes the ship move-- just not in the direction you wanted it to. It still stays to the right of the screen.
Help is appreciated. I love classic gaming, but anything before NES is out of my era and expertise. Thanks in advance.
