redalert: MAME ROM Information.

History:

Red Alert (c) 1981 GDI, Inc.

FIRST ATTACK IN DAYLIGHT - BOMBERS IN FORMATION WITH ATTACKING AIRCRAFT. This sequence is introduced both audibly and visually : Red alert. Enemy aircraft approaching. 20 jet fighters approaching. Destroy all fighters by 11:00 hours, or MIRV will be launched.

In this sequence, bombers in formation move from left to right across the screen, and then from right to left, etc. During the attack, some break formation and attack the launcher. The aircraft drop bombs in an attempt to hit the launcher. Also during the attack, a special red colored aircraft flying above the aircraft formation appears and drops a red colored megaton bomb that slowly descends on the country. When hours reach 11:00, present fighter attack is interrupted by a flashing CAUTION on screen, followed by appearance of the MIRV.

The MIRV slowly descends, then breaks up into several bombs. They, in turn, also break up into several bombs. As a result, a shower of bombs slowly descends on the country.

Player participation during the attack is to destroy all aircraft by firing rocket launcher. During the attack, player is to avoid direct hits by bombs - each of which costs him one rocket launcher. Also during the attack, the player must destroy the red bomb before it lands, or one rocket launcher is destroyed.

When MIRV appears, player must destroy it completely - otherwise the landing of any one will cost the player one launcher.

SECOND ATTACK BY HELICOPTERS - DROPPING PARACHUTE BOMBS. Introduced by : Helicopter squadron attacking! Destroy helicopters by 16:00 hours, or MIRV will be launched.

Player participation during attack is to destroy all aircraft by firing rocket launcher. During the attack, player is to keep his launcher away from red areas created by exploding bombs - or lose a launcher. Both helicopters and bombs may be destroyed by rockets. However, if the parachute, but not the bomb, is hit, the deflated parachute will drop the bomb much faster.

MIRV attack, if launched, is a repeat of the first sequence above.

THIRD ATTACK AT NIGHT - HEAVY BOMBERS IN FORMATION. Introduced by : Red alert. Night attack by bombers.

The player is aided by two searchlights. The object is to destroy all aircraft. When all aircraft are destroyed, game progresses to next frame (country). During the attack, the player must avoid direct hits by bombs. No time limit is imposed. No MIRV will be launched.

GAME FRAMES. Game repeats above cycles through the following countries, respectively : FRANCE, USA, ITALY, GREAT BRITAIN, GERMANY, and JAPAN. However, as the game progresses from frame to frame, the action of the game is stepped up.

HOW LAUNCHERS ARE LOST. Rocket launchers are lost by :

* A direct hit by a dropped bomb

* Red bomb dropped by red plane lands anywhere

* Launcher is in red area created by exploding parachute bomb

* MIRV lands anywhere

MAME Info:

0.33b3 [Mike Balfour]

WIP:

- 0.144u6: hap changed 'WW III' to a clone of Red Alert.

- 0.127u1: Added missing SHA1 values to WW III.

- 0.127: Stefan Lindberg and Couriersud added 'WW III' (Irem 1981). The PCB is not working so Stefan Lindberg don't know if the roms are fine, the sound rom was for sure bad it gave different checksums but most of the reads matched the MAME soundrom (Red Alert) it is marked exactly the same "w3s1"(IC5). The BPROM matched the Red Alert set also. It's hard to see because the sticker has been damaged. The other Eproms exept one did not match anything in MAME, and only one of those had the Eprom type markings on it.

- 0.122u7: Rewrote and modernized the redalert driver [Zsolt Vasvari]: Correct colors, in places different from the manual's description, but matches the flyer perfectly. Added speech. Fixed AY-8910 sounds. Odds and ends. Fixed saving I8085 callbacks across a reset. Added 'pull' callback for the SID pin. This is needed by the Red Alert voice board. i8085.c updates [Couriersud]: 8085 has an internal clock divider by 2. Changed i8085.c to reflect this for I8085. I8080 still at 1. Changed driver clocks to reflect internal clock divider. Added some FIXME: Comments where clocks for I8085 are outside specs. Fixed cpu2 rom address to $7000. Added HC-55516 (23437 Hz) sound. Changed M6502 CPU1 clock speed to 781250 Hz, M6502 CPU2 to 1041666 Hz, 8085A CPU3 to 6MHz and AY-3-8910A to 2083333 Hz.

- 0.74u2: Added prom ($0 - unknown) and dipswitches 'Cabinet in Service Mode' and 'Cabinet'.

- 1st October 2003: Pierpaolo Prazzoli added cocktail mode to Red Alert.

- 0.35b8: Replaced 8085 CPU3 with 8085A.

- 20th April 1999: Brad Oliver updated Shark Attack and Red Alert for proper rotation support.

- 0.33b5: Added I8085 CPU3.

- 0.33b4: Red Alert accepts coins now and fave better colors [Mike Balfour].

- 0.33b3: Mike Balfour added Red Alert (Irem + GDI 1981). Everything in this driver is guesswork and speculation. If something seems wrong, it probably is.
