I just came across this thread and have a Vorke Z6 Plus with CoreELEC 8.95 on it so I thought I would try to get this working. I installed CoreELEC 8.95 with the DTB gxm_q201_3g_1gbit.dtb and it works great, even working with my Vorke remote which LE didnt.
Anyway I installed OpenVFD from the CoreELEC repo and copied vorke-z6-vfd.conf from the link in Post #1 to \\mybox\configfiles and I rebooted and immediately the time came up.
Great work guys! Thanks very much!
Do you have working icons on your box? My TX92 (similar to Vorke) only has working clock and display modes (temp, playback time, etc)
