Fixing the Missile Command bug

[Lumpbucket]

As there are lots of talented 6502 programmers, who are also Atari fans, here, I thought you might like to know of an effort to fix the extra bases bug in Missile Command on another forum:

I get a gateway timeout when I click on that link.

 

What Missile Command bug?

Odd, the link works fine here.

 

When you get 800,000 + the "extra bonus" interval (set on dip switches) it erroneously gives you 176 extra bases, and also 156 when you wrap the score.

 

Initially they were just wondering exactly what caused the bug, for the sake of interest. Now, being programmers, they noticed that it would be a bit tricky to fix the bug and keep within the ROM size. And you know programmers when they're presented with a challenge

Uhm... i mean "bonus cities" not extra bases. Probably. I'm not up on all the Missile Command jargon :-)

Hi there!

 

Also I think the information Tempest was actually looking for was "Arcade"

I've heard of this bug, but since I could never in a million years get that high I never really cared much. I'd be interested to hear what they find out though.
