2600 Rom Comparisions and Dumps
This thread is devoted to comparing the old era roms of the atari 2600 library. Have you ever wondered why there is 3 versions of a particular rom with no visible differences? Well you're not alone!

- Bank 1 (normally $1FF9) ---> now is $02A0
The other actual differences were just in the logos and text. You can see the differences below:
