hi there! i'm a noobie on this forum, but am loving this so far. i'm an american aristocrat player, started with mk6, but have played mk4 thanks to mame! i'm wondering how to start the games from the mk5 series. i know the combo to start for mk4 which is holding j and k, with z x and c, but just how do you get the mk5 series to work and except credits. what is the mk5 keyboard layout. i've seen those mk5 machines roaming around vegas, i think, we had a whole load of those guys in a local california casino in about 2003 to 2008. even though i wasn't age aproved yet, just loved the music and sound of the machines. faves being the unicorn, honky-tonk, addonis, queen of the nile, king of the nile, geisha, enchanted forest, and where's the gold. i'd love to play those machines with granny while i'm down at her place. but the ones i hope they add are the unicorn, return of the samurai, and penguin pays. granny used to play the heck out of penguin pays, used to walk past that machine without at least hearing one of those penguins honking.
