emptyx16: A Complete, All-in-one X16 Hardware Reference


Recommended Posts


First time posting here. So basically I have a game project coming that targets a retro machine with quite capable graphics and sound. Which I found this system to be a good start. However, the current x16-docs hardware reference is quite hard to navigate and lacking in some details. Inspired by hardware references I usually use for Gameboy and SNES programming, I decided to spend few weeks and write my own X16 hardware reference. Which is now available in both (printable) HTML and plain text here:



Note that this will be updated once I can confirm more details and a hardware itself is finalized (no, please don't reply about that leak here). So please look forward to it. The document's source is also available here and everyone is welcome to contribute.

Reminds me of the old days, when you had the official Programmers Reference Guide but there were also tons of third-party books that all had their own way of explaining things.

Reminds me of the old IBM Reference docs that were distributed on CDROM back in the day, for mainframe development, DB2/UDB, etc.

Also a request, make the left/right frames resizable by dragging a handle between them.

I don't see your document mention the default palette RAM values on reset.

Oh right, thanks for reminding me to document reset values.

This would require some JS inside the page though but doesn't hurt to try.
