OK, I just spent several hours trying EVERYTHING and looking at dozens of old threads trying to get Demul to run a game from AM. Nothing works!
I'm using the latest AM, and the latest Demul build (.07 111117).
I can run Demul games direct from Demul, no problem. I can launch Demul games from a command line (i.e. demul.exe -run=awave -rom=dolphin).
But nothing I try runs a game from AM. What I get is the demul game selector Window for whatever system I'm trying to run (i.e. awave, naomi, dc etc.), instead of the specified rom/image running.
PLEASE, if you can actually run Demul games from AM, I beg you... please share your voodoo!
