Hi everyone. I've been lurking on this mailing list for a few days and now seems like a good time to join in.

I just got a Brazillian "Supergame" system, which I believe is a version of the Coleco Gemini. So I decided to give the test program a try using my Supercharger.

First I tried it with my 2600 Jr., and to my surprise the test failed (brownish red color. Then I tried it with the Supergame system, and it succeeded (blue color). Then I tried it with my second 2600 Jr. and my 4 switch woody. They both failed too. I then tried the Supergame system again, and it failed.

Now I was starting to wonder if something was wrong with my supercharger, so I tried playing Missle Command through it. It worked fine on both my jr and Supergame. I then tried the original test program Dennis originally posted. The illegal opcode version worked twice on the supergame, and failed twice on the 2600 Jr.

So I figure either I'm going crazy, my supercharger setup is somehow wrong, or this opcode is very unstable. What you do you all think?

I'd especially test the Coleco stuff, this Gemini thing and the 2600 expansion module. Also it might make sense to test it both on a kool-aide Jr. and a non-kool-aide Jr. and maybe some of these pirate clones with XXX built-in games.
