Thanks for the good suggestions ...

An RPG (role playing game) -- would probably be the easiest introduction to scrolling techniques I think. Tile graphics with maps, and as such, Pacman uses a map, but without the tile graphics.

I have some good joystick routines actually, and perhaps a chapter which deals strictly with IO could be some food for thought.

I have nothing set in concrete at the moment, besides around 90% of 3 of the games completed.
