S.C.I. - Special Criminal Investigation/Gameplay

Controls

• Steering Wheel: Use the steering wheel to direct the car left and right, just as you would with any real car; in MAME, this is replicated by the left and right arrows, but after the Turbo Activator has been pushed the car becomes harder to steer due to the fact it has accelerated to an incredible speed.
• Gas Pedal: Step on the gas pedal to accelerate the car; in MAME, it is replicated by Ctrl by default but you may wish to change it to the up arrow. A virtual break pedal is also present for the emulated cabinet, and replicated by Alt by default (but you might wish to change it to the down arrow).
• Firing Button: Use this newly-added button to make Gibson stick his head out of the car's sunroof and fire his gun at the randomly-generated CPU-controlled cars and other obstacles to destroy them; in MAME, this will be replicated by Space by default but you may wish to change it to Ctrl.
• Gear Shifter: Use the gear shifter to change the gear the car is driving in; in MAME, it is replicated by pressing and holding Shift to shift into high gear by default (then letting go of it to shift back to low gear again), but you may wish to change it to Alt. Pushing the shifter's Turbo Activator will also, for a maximum of three times per stage (now indicated by the text "X BOOST" in the bottom-left corner of the screen), accelerate the car to an incredible speed for a few seconds - and in MAME, this switch is replicated by pressing Z by default but you might wish to change it to Space.
• Start Button: Push this button to start the game; as with several other racing games that do not support link plays, this game is for one player only.

Patrol Car

This red Nissan 300ZX T-Top Turbo is the new car for the protagonists, Tony Gibson and Raymond Broady (also known as Mr. Driver); the player must, again, help them catch up with various criminals' cars (which will be indicated by an arrow with the text "CRIMINAL" appearing above them once they are caught up with) within a minute, after which a flashing blue light appears on its roof and its siren starts to get heard from the Yamaha YM-2610. They must then hit the criminals' cars until they are too damaged to keep going (while avoiding contact with all the other vehicles as they will cause it to spin out or go off the track, which costs time) within another minute - and as with the custom black Porsche from Chase H.Q., the car also has a Turbo Activator which can be used to make it accelerate to an incredible speed for a maximum of three times per stage and it must for a second time be used wisely to catch the criminals before time runs out. However, Gibson can now also stick his head out of the car's sunroof and fire shots from his gun (first used by him and Broady in the spin-off game of Crime City earlier in 1989) at the randomly-generated CPU-controlled cars and other obstacles to destroy them; it's also worth noting that if the arcade operator has set the "Turbos Stocked" dip switch setting to "5", you shall get five Turbo Activator uses per stage, but on the sixth and final stage, you will only get one regardless of how the cabinet is set, and it must be used as you cannot clear the stage otherwise.
