ProtoGame Quadriple

Trivia

 * There is a Qsound Add-on in 1992 to enhance the sound to make it sound like the Capcom CPS2
 * The Console has an Extra Q-Sound Screen before booting the game with it's own jingle (Credit to marbardan, no infrigment intended) if the add-on was inserted, it is also unskippable
