Release notes from Phry:

Hello there.
(sorry for my bad english)
That is my third atari 2600 project. Its an attempt to create a demo. The source is very big and i think it can be optimized. Can somebody tell me how i can create this effect without writing every frame as a new playfield?

Thanks a lot!
