Bob,

I wrote the attached code some time ago to display a scrolling maze.
I don't think it will directly be useful to you as it was one of my
first 2600 projects and the code is not particularly high quality, but
the scrolling is very fluid and it might give you some ideas.   I
ultimately abandoned it as there wasn't sufficient memory on a regular
2600 to display enough tiles (currently there are just 6x5 tiles on
screen), though this shouldn't be such a problem with the SC.
Horizontal scrolling is achieved by ror/rol-ing the tile data across
the screen, and vertical scrolling is accomplished by changing the
starting address of the screen (using a circular buffer).
