Thanks for the reply and yeah its understandable that it would have to be made outside of VCS maker. The reason why is by doing that and stretching the sprites to be wide. Its possible to have a full bitmap of graphics on a stock atari 2600. Yes the CPU will be doing a lot of rendering work. But it would be possible to then create a RPG world because of how quirky the 2600s rendering is.
You're welcome! What you describe kinda sounds like Batari Basic's Title Screen Kernel, but more dynamic:
