As Vas already said you must use the 'AES' machine, not the 'NeoGeo' machine.
the hardware is different (Aes lacks things like the watchdog timer) MAME treats them as different machines.
other emulators use hacks to represent them as a single machine, MAME does not, the original machine did not determine this with dipswitches which is why you don't see any in MAME for it.
'mame aes samsho4' from the commandline for example will launch the home / aes version of samurai shodown 4.
