S.C.I. - Special Criminal Investigation (c) 1989 Taito.

A direct sequel to 1988's "Chase H.Q.", S.C.I. once again puts the player in charge of an unmarked police car - this time a Nissan 300ZX T-Top Turbo - in which the player must chase and capture a criminal mastermind before the time limit expires. Graphically, S.C.I. is very similar to its predecessor, although there are slight improvements with both a better use of colour and the introduction of some new weather effects; such as the rain on the first stage. Unlike the first game, the player is armed with a gun; this is used to take out criminals and roadblocks as the player races against the time limit, and also to capture the criminal mastermind and make an arrest before the time limit expires.


This game was available in at least 3 different dedicated cabinets, plus it was also sold as a conversion kit for "Chase H.Q".

* The sitdown version is a strange plastic monstrosity with a huge monitor. This may have been a Japan only release, as the cabinet looks very similar to the popular Japanese cabinet style.

* The standup versions are all very solid wooden affairs, covered with full painted sideart (very few games still used painted sideart in the late eighties).

All versions use Happ Controls force feedback steering wheels (the ones that can spin all the way around), a high low shifter (different versions had this on different sides), and a single pedal.

A little known trick (or is it a very generous bug?) to this game : Start a new game, and accelerate VERY slowly until your score reaches 90. Now STOP and just let the time run out. Once your game ends, don't continue, just let the timer run down. Once that happens, you'll notice that your score will SKYROCKET to the ridiculous amount of 76,543,210. Now go ahead and claim your top spot on the hi-score table (cheater!@#).

- 0.119u1: Team Japump added clone Special Criminal Investigation (Japan). Fixed rom names.

- 0.84: Brian Troha improved dipswitches in SCI. Changed 'Respond to Controls' dipswitch to 'Steering Radius'.

- 0.37b13: Changed description to 'Special Criminal Investigation'. Renamed Testdrivers (chasehq2) to (sci), (chashq2a) to (scia) and (chashq2u) to (sciu).

- 0.37b11: David Graves added Chase HQ 2: SCI (World set 1) (Testdriver) and clones (World set 2) and (US). Known issues: No road. Wheel control poor-ish. Sprite frames were plotted in opposite order so flickered. Reversing this has lost us alternate frames: probably we have to buffer at least one half of sprite ram?


- Player controled two cops, the first would drive a Nissan 300ZX T-Top Turbo in pursuit of the suspect vehicles, and the second would stand up in the passenger seat and fire upon the enemy cars, when the player pressed one of the steering wheel's trigger buttons.
