I've recently been playing 2600 Activision titles to achieve the "patch" scores. After I achieved the Beamrider score, out of curiosity, I checked to see if there was a speedrun page for this game. Pleasantly surprised. But I suspect the difference between some ports might give one an advantage over another. The start and end frame in the rules don't even occur on the 2600 port. It's fairly clear to identify the frames when the run starts in this video, and when Sector 6 begins:

Using somewes' frame-count website, I get a run time of 4:41. It doesn't seem fair to compare this to ColecoVision runs, as the time between Sectors is smaller. On the other hand, I don't really see this game ever being popular enough to mandate separate leaderboards.

Just curious as to what others may think. I'll hold off on submitting the run to this leaderboard until some acknowledgement of this post is made.

Thank you.

I went ahead and updated the board to add an Atari 2600 category. It's simple enough to do, and will add other game categories as people request.

And apologies for the late response; src apparently doesn't notify me about forum posts in games I mod... may have to fix that
