Oh, my bad, I was suggested by the Atari font, but C64 was similar. If you could make it for the Atari/C64 it would be great. There are still many people loving these computers and developing new games so I’m sure there would be many eager players for your game!
I agree. I've hobby developed for the C64, NES, Apple II, and Atari 2600, but not yet for Atari 8-bit. But that's not to say I haven't studied up on it. And I purchased a copy of Mapping the Atari. I think you are right that it would suit the Atari computers. So I will give it a shot when time permits.
