Hi everyone.

Recently I coded Toledo Atomchess 6502, a basic chess game with graphical board for Atari VCS/2600.

All the source code is available at https://github.com/nanochess/Atomchess-6502

I've wrote with it in mind for the Hackaday 1K challenge where I've entered it.

The hardest part was to fit the graphical chessboard as the Atari doesn't provide any support routines and the TIA is very primitive. It works very well for its size.

I've made a video showing it in action https://www.youtube.com/watch?v=_Du4krvIl7o

Enjoy! :)

Ouch! I wonder how hard it is to put that video through a slow persistence-of-vision filter? I had a quick play with vlc and ffmpeg but got nowhere.

Have you seen the original Computer Chess which uses a venetian blinds effect to make the game pieces from the player graphics?

I've saw it, my problem here was lack of space.

Edit: Youtube removes frames from the 60hz source to make it 30hz, my solution in the meanwhile for the video would be a program that could mix consecutive frames to provide 30hz to Youtube.

It's just possible that Youtube haven't yet transcoded this video to full framerate - if you can be bothered, perhaps you could try uploading a much shorter one and see if that comes up. Searching suggests that at one time it helped if you go into Edit, Enhancements, play a bit, then Save - it forces a requeuing of the processing. But longer videos take longer in the queue. It is possible to get a 60fps playback, but for this video it's not (yet) available.

Uploaded a new video in the right size so Youtube gets it at 60hz. :)
