Instead of a full list of systems, we'll choose a few highlight systems and then have a full list of chips for reference. (Everything else is commented out for now. for convenience.) What systems should be added or removed?
Oh, and the little empty comment lines provide list grouping while keeping the lists more compact, at least for GitHub's Markdown reader.
Added spacing to make it easier to work with the document.
Also, I keep doing that thing with the SNES where I put "SPC700" but really should just put "SNES". Bad habit. (The real reason for the commit.)
The idea: list all the systems shown in the "new file" dialog, link to their chips.
Also, moved all the important info out of genesis.md and removed it, finally!
Also also, fixed the tiniest issue in the credits. 😊
