I mapped this Atari 2600 game and is submitted to Jon Leung.
Here is a scaled down preview of it here.

That looks pretty large for an Atari 2600 game.

The map dimensions are 2520 x 1456 and the sections are 304 x 1408 each. The sections scroll vertically but not horizontally. The features in this game are quite advanced especially the soundtrack.
