best port offline? its simple - mame! i've played mkak ps3 and as some people already said it has IN BUILD delay even offline... wtf? i couldnt do simple jk, afb after popup combo...
the pc version seems legit, but it feels slower than mame, and it randomly crashes sometimes without reason, so you need to restart it. also it has issues with almost all pads, except 360. a good plus for me is that you can edit game's config, maybe soon people would be able to unlock chars in single player, adding hsmoke and maybe even playable noob.
havent played the 360 version, but comparing mame, mkak pc and mkak ps3.... all the way mame, there is no even debate. i think the only thing that can beat mame is real arcade cab.
edit: thats for umk3. mk1, despite the ridicules new and ugly sounds and glitches, and the delay for ps3 version, the PC MKAK looks fine for me.
