Sorry I didn’t realise you were still struggling here.
I’ve just tried Monkey Island for you on my build there and it’s working.

Not had much traffic there unfortunately!

Make sure you follow the instructions at the top - specifically don’t do a bulk install (basic install). Do everything individually, most importanly emulationstation-dev (not the regular version).
