I have generated a config file for my Beelink GT1 and GT1U remote. I think the ir codes are the same with the Mini MV III II. I have mapped a few keys to use it with Libreelec. Please take a look in the beelink_gt1 file.
Hello nice, I also have the Beelink GT1 Ultimate and my remote does not work on Coreelec 9.0.1.
I do not know where to put your "beelink_gt1.zip" file. I was looking for /storage/.config/rc_keymaps but did not find it.
Can you please write me exactly where to put it. I do not understand much.
Thank you for the information
