@hermine.potter:
My mame 0.185 doesn't react to a normal TERM signal, e.g. "kill $(pidof mame)". Only the KILL signal ends the mame process, e.g. "kill -KILL $(pidof mame)". Thus, in case AM tries to end mame with TERM, it won't work because of mame ignoring it. To my knowledge, this is not a typical behaviour for a Linux program. Most react to TERM with termination.
Could you test it with other emulators?
And how does one report those issues to the AM developers?
