Thats exactly what I did. Found a female 9pin with long leads(i think they were about a foot long), and conencted the correct wires right to my wiring block. Right now the 9pin connecter is dangling inside my cabinet, but eventually Ill get it mounted somewhere.
That way when playing Atari roms, the Activision collection, or even mame games with 1 button, Ill be able to kick back on the couch like the good ol days
