yep.
i believe that was posted a few times
one thing though... you also need to disable a few keys in zsnes ... it has the same keys as mame button values (1, 2, etc) assigned to some zsnes tuff by default.
to dol so you go thru the misc menu in zsnes and unassign keys for all that stuff.
at least i had to do that on my cab
and then yes, set disablegui to 1 to allow mala to close zsnes and return to the list (enable close wrapper/hook in mala to the 249 key)
good luck!
