# Dragon 32/64 Keyboard to USB Keyboard suitable for XRoar with translate OFF
#	Wayland, Robcfg
#
# Uses KMK Librarys for PI Pico.
# Uses Lee Smith's C64 PCB layout https://github.com/midicdj1000/RETRO-PICO-KMK-Keyboards
#
# The symbol keys do not actually return what's printed on them except in XRoar 
# which knows what they are supposed to do on the Dragon.
# 2023/04/15 Mostly working. Problems with some symbols, £ @ * =
# 2023/04/16 Works with XRoar. Everything except @ which comes out as "
# 2023/04/18 Finished for XRoar. All keys working.
# 2023/06/29 Modified config so that it works with all keyboards and doesn't need
#            to modify XRoar's config to get the @ symbol.
