[run & gun 1/2]

well run and gun 2 doesn't work but run and gun does work very good on mame v078. what you have to do is when load it up just hit ok to get by that redump question then at the eprom check hold F2 then press F3 like one or two times. then when rom loads again it will load up. to play 2 player always choose play independtly then once you start playing just have the other person join.

[run and gun]

well run and gun 2 doesn't work it starts to load but just loops the memory check or whatever screen that is. however run and gun 1 works fine on mame v078.
