KeysMeConsole keyboard software
sharkfin is a free, open-source replacement for the KeysMeConsole app: remap keys, set the RGB, paint per-key colour and record macros on 2 KeysMeConsole boards, 0 of which accept changes. Use it in a Chromium browser with nothing to install, or as an app on Windows, macOS and Linux. It runs entirely on your own machine, with no account.
Does sharkfin support my KeysMeConsole board?
The table lists every KeysMeConsole model sharkfin knows, 2 in all. Between them: knob. If yours is missing, plug it in anyway: these boards report their own device id, and sharkfin identifies anything built on ROYUAN hardware from that reply, works out which command set it speaks, and asks before it writes.
"Writable" means sharkfin will change settings on it. Read-only boards are ones whose command set is not established yet; sharkfin identifies them and reads from them, but refuses to write, because the two protocol families in this hardware share opcodes that mean different things.
