I am coming close to finishing my mame cab.  However, i am a SF3 junkie and want to somehow incorporate this into my cab.  
I believe the cheapest way to do this is by hacking a DC.  
My question is...  Is it possible to make it easy to switch between a hacked DC setup and my mame computer?  I mean, without having to spend 20 mins switchign wires and whatnot?  Is there some sort of adapter, switch or something?  Thanks in advance.
