The 2600 has a chip called the TIA that handles all graphics and sounds. It has it own registers that handle players, enimies, balls, missels, and playfield. The A,X,Y registers are used for math, reading the TIA, ect.
Please check out the Atari 2600 SDK that I put together that will ansewer
all your questions. And contain everything you need to write/test your code.
In DOS only sorry.

Read the Stella Guide - Our Bible it will ansewer all your questions.
Good luck.
