- TRIVIA -


Released in May 1981.


This game is an enhancement hack of "Missile Command".


GCC [General Computer Corp.] was founded in 1981 during the onset of the video game craze. C.E.O. Kevin Curran and MIT classmates Doug Macrae and John Tylko began by developing an enhancement for Atari's "Missile Command" and went on to create "Ms. Pac-Man", still one of the top-selling coin-operated video games in history. Between 1982 and 1984, GCC developed a total of 58 consumer electronics products that generated over $800 million in revenue for Atari and Bally Manufacturing.


- UPDATES -


Differences from "Missile Command" are :

* A new look to the game : different colors, different attract mode, etc.

* A new play to the game : more missiles, faster missiles and clouds that get smaller as the game goes on add challenge (and profit) to your Missile Command box. Plus a Totally New Attack Object, the 'UFO', which moves faster and more randomly than ordinary planes and satellites and fires a deadly new Laser weapon.

* A new sound to the game : each attack object now has its own brand-new sound that lets everyone know that this is no ordinary "Missile Command".

MAME Info:

0.143u1 [Joe Barbara]

0.26 [Ray Giarratana]


Artwork available


WIP:

- 0.146: Couriersud improved sound emulation for POKEY chip. Changed audio emulation to emulate borrow 3 clock delay and proper channel reset. New frequency only becomes effective after the counter hits 0. Emulation also treats counters as 8 bit counters which are linked now instead of monolytic 16 bit counters. Fixed high pass filters for POKEY. Added POKEYN device based on modern device. Fixed random lfsr generation. Consolidated polynom code. Removed legacy left overs from pokey code. Added a internal pokey_channel class. This fixed imperfect sound play in Missile Command for UFO and bomber attack. Convert all remaining drivers to use the modern pokey device.

- 0.145u7: hap changed manufacturer of clone Super Missile Attack to 'Atari / General Computer Corporation'.

- 0.143u4: f205v and robotype added clone Missile Combat (Sidam bootleg), not working.

- 0.143u1: Joe Barbara added Missile Command (rev 3). Changed 'Missile Command (set 1)' to clone '(rev 2)' and clones '(set 2)' to '(rev 1)' and 'Super Missile Attack (for set 2)' to '(for rev 1)'. Renamed (missile2) to (missile1) and (missile) to (missile2).

- 0.140u3: Kevin Eshbach corrected Missile Command and clones ROM locations and added proms ($0, 100) to clone Super Missile Attack (for set 2).

- 17th December 2010: Smitdogg - Kevin Eshbach dumped the proms from Super Missile Attack.

- 0.133u1: Renamed (sprmatkd) to (suprmatkd).

- 0.128u4: Derived clocks from crystals in Missile Command [Luigi30].

- 9th July 2008: Mr. Do - Added cocktail artwork to Missile Command, vectored by Zorg.

- 0.116u3: David Haywood added clones Missile Combat (Videotron bootleg, set 1) and (Videotron bootleg, set 2).

- 13th June 2007: f205v dumped Missile Combat (Videotron bootleg, set 1). PCB is marked: "VIDEOTRON BOLOGNA 002".

- 0.115u1: Aaron Giles fixed corrupt graphics in Missile Command.

- 21st January 2007: Mr. Do - Thanks to the loan by Vintage Arcade Superstore and vectorization by Jcroach, we finally have a completely accurate Missile Command bezel. I put two views in this one: Actual arcade and a second to maximize the artwork to the screen.

- 20th August 2006: Mr. Do - Fixed the font in Missile Command bezel.

- 15th August 2006: Mr. Do - I re-did Missile Command from scratch (the bezel is text only).

- 0.107: Rewrote Missile Command driver from schematics [Aaron Giles]: CPU speed now correct (slows down for lower 32 scanlines), proper frame rate and IRQ signal timing, service mode works on some sets, fails on others due to 6502 bug, accurate bitmap mapping and cycle counts for 3-bit accesses and using bitmap access PROM for bit mode writes. Changed M6502 CPU1 clock speed to 1250000 Hz and VSync to 61.035156 Hz. Added 'Service Mode' dipswitch.

- 0.104u3: Aaron Giles fixed save state support in Missile Command.

- 15th January 2006: f205v dumped Missile Combat (Videotron bootleg, set 2).

- 0.101u4: Aaron Giles fixed Missile Command stays at black screen.

- 0.101u3: Buddabing added preliminary save state support to Missile Command.

- 0.92u1: Mowerman and Dave Widel added clone 'Super Missile Attack (for set 2)'. Changed description of clone 'Super Missile Attack' to 'Super Missile Attack (not encrypted)'. Renamed (suprmatk) to (sprmatkd).

- 0.92: Highwayman added prom ($0 - sync).

- 0.34b3: Nicola Salmoria added clone Missile Command (set 2). Changed parent description to 'Missile Command (set 1)'.

- 0.31: Mike Balfou added clone Super Missile Attack (Atari + Gencomp 1981).

- 0.30: Fixes to Missile Command [Eric Anschuetz].

- 0.29: Marco Cassili fixed dipswitches in Missile Command.

- 0.27: Ray Giarratana included trackball support to Missile Command.

- 0.26: Ray Giarratana added support for Missile Command (Atari 1980). Game is playable with accurate colors and sound. Mirko Buffoni didn't include modifications for trackball for now. The code needs to be cleaned a bit, but the game is still playable. Control: A,S,D = Left, Central, Right shot.

- 18th December 1992: Dumped Missile Command (set 1).
