So I have done the following so far:
1. Installed RGBCommander
2. Updated config for 2 U360
3. Tested that I was able to change mode on sticks via rgbcmdcon and jstest/jstest-gtk
4. Added "output network" to mame.ini
5. Ran procdiff to get mame process name : mame64
6. updated emulator config in xml and restarted
I don't see anything in the logs that shows me that it sees the mame process , when I launch a rom manually from the command line . Am I missing something?
