I just did my first VCS game "Refraction". It's a two players game about a basic duel with a twist (6502 assembly, simple 4K cartridge).
The game can be found here (Javatari preview and binaries): http://www.masswerk..../04/refraction/
It has been done as part of RetroChallenge 2018/04 over the course of April, which might be of interest here insofar as maintaining a blog or some kind of write-ups on the subject of the project is a basic condition of RetroChallenge. So there's a dedicated blog, where I try to explain, what the VCS is all about and introduce some of the basic concepts:
(I had some unexpected issues with the Battlezone repositioning routine and ended up with my own version and a some peculiar offsets for specific objects – 1px for missiles and the ball, 2 pixels for player sprites –, compare Episode 6. )
Finally, I did a small application for testing sound, "Studio2600": http://www.masswerk..../04/studio2600/
(If you're using this as a musical instrument on stage, be sure to post a video! )
Since this project has been some fun, others may follow. E.g., a Computer Space simulator for the Atari 2600.
(I have done one for the PDP-1 – running at 60 frames per second on a computer introduced in 1959! – and a character based one for the PET 2001. The Atari 2600 deserves a version of its own, for sure!)
P.S.: I also made a tiny, web-based sprite editor for this (maybe useful): http://www.masswerk....nySpriteEditor/
