The trick is the Controls and game settings (Score 1)

I found building my mame machines to be a lot of fun. I converted a Tekken 3 into a full fledged mame machine. I did spend much time getting the controls just right. Using 8 way joysticks in 4 way games will really frustrate a person. I found the Ultimarc 360s to be the easy solution. The key is to have the game switch joystic modes automatically. Another key to the arcade experience is to throw at least one Pinball machine in the room. Respect!
