Made a quick and buggy (hah) Frogger.
I wanted to try an hypothesis: I don't think that in the Atari version they do any collision detection at all. Instead, they may use a formula to check whether current position is occupied by an item or not.
Formula in function positem() returns an x position depending on a direction, speed and offset, and is used to draw items and also for checking if there is something on frogger's position (checkrow())
