I have wired Xbox 360 controller and all the emulators work fine but "Final Burn Alpha" and maybe some of the "MAME Emulators".
When starting a ROM it will flash yellow with "Microsoft X-Box 360 Pad (1118/654) not configured".
I tried Googling this exact phrase or around these words with no avail.
I've also read here: https://github.com/retropie/retropie-setup/wiki/Xbox-360-Controller
I tried changing "udev" to "sld" and back again
I tried using "Xpad" and "Xboxdrv" drivers
I tried unplugging and plugging in back again again
I tried a different controller
On the wiki it has a section about "Xbox 360 Controller button configuration for retroarch and final burn alpha" but perhaps I don't understand it.
Should I ensure these these config files have the same settings as the wiki?
/home/pi/RetroPie/emulators/pifba/fba2x.cfg (or /opt/retropie/emulators/pifba/fba2x.cfg in some versions)
Any suggestions or anything I should test I would appreciate it.
