After a couple of hours playing about with my old MOSC, it finally updated with the keys, just finished manually adding the keys (Excw) to my Atmega. Been a while since I had so much fun.
Just did some logging a while ago and had a look at the EMMs, it should be an easy fix for funs and atmegas as most of the code is already present in 1 form or another, simple copy, paste and minor changes should do it.
