@chubsta said in ZX Spectrum keyboard - Pi400 mapping:
Even just a printout which shows which keys on the Pi relate to which keys on the Spectrum would be a nice start as I currently struggling to marry up the keys on the Pi with what I would like to achieve on the 'Spectrum'.
Assuming you're using the fuse core, I don't think the mapping is that complicated. The core docs show the keyboard is sent as is, but I assume this applies to the core when game focus mode is enabled in RetroArch. Unfortunately, the PI400's keyboard doesn't include the 'Scroll Lock' key which is used by RetroArch to toggle 'game focus mode', so you'll have to rebind it to another key.
Alternatively, you can give Zesarux a try and see how it fits with the Pi400.
