0.119u3 [Arzeno Fabrice, Chris Hardy]

0.78 [Olivier Galibert]


Bugs:

- Side by side test comparison. Kale (ID 06379)


WIP:

- 0.143u5: MASH fixed graphic artifacts and speed drop during gameplay in Crack Down.

- 0.128u4: David Haywood replaced parent Crack Down Floppy image with one containing valid settings data (prevents game booting with 0 seconds and invalid highscore data which it can't restore correctly).

- 0.127u2: Changed description of clone (Japan, Floppy Based, FD1094 317-0058-04b) to 'Crack Down (Japan, Floppy Based, FD1094 317-0058-04b Rev A)'.

- 0.121u2: Added 3rd button and coin slots 3 and 4. Changed description to 'Crack Down (World,Floppy Based, FD1094 317-0058-04c)' and clones (US, FD1094 317-0058-04d) to 'Crack Down (US,Floppy Based, FD1094 317-0058-04d)' and (Japan, FD1094 317-0058-04b) to 'Crack Down (Japan,Floppy Based, FD1094 317-0058-04b)'.

- 0.119u3: Arzeno Fabrice and Chris Hardy added Crack Down (World, FD1094 317-0058-04c). Renamed (crkdown) to (crkdownu).

- 0.101: Added new disk image ds3-5000-04b.img to clone (Japan, FD1094 317-0058-04b).

- 0.100u1: David Haywood and Team Japump added clone Crack Down (Japan, FD1094 317-0058-04b).

- 6th August 2005: Dave Widel - I've sent a Crack Down cpu and disk to Charles for dumping. Hopefully that will resolve the problems with it in MAME, whether it is a disk error cpu decryption error.

- 0.99: Nicola Salmoria and Chris Hardy fixed 1-bit errors in decryption keys for Crack Down.

- 0.95u6: Changed description to 'Crack Down'. Removed 3rd button. Added 'Flip Screen' and 6x 'Unused' dipswitches.

- 0.95u2: David Haywood attempted to fix crash in Crackdown.

- 4th April 2005: Dumping Project - Randy have won a board that was supposed to be 'Scramble Spirits' but turned out to be 'Crackdown' (contributing to the recent progress in the emulation of that game).

- 0.95u1: Charles MacDonald dumped the FD1094 key for Crackdown, it appears to decrypt the disk image recognised by MAME, although there are a number of glitches which may be due to bad system24 emulation, or a bad disk, and it crashes when you attempt to start the game. David Haywood figured out where the missing Sega logo was, Crackdown doesn't seem to like the current sprite clipping implementation in the System 24 driver, however, he don't think its an identical version to the one shown at System 16 because the Sega logo is never shown against the wall (unless the shot for the flyer used at S16 was doctored which wouldn't be uncommon for flyers). He also worked out why the game crashed, it needs valid default settings. Factory defaults can be restored in the service menu, however, this doesn't restore the default high scores which are lost forever once somebody beats the top 3 so the chances of us finding an unused Crackdown disk with original high scores intact seems somewhat hopeless. Anyway, aside from a few graphical glitches (the mentioned clipping, and a transparency, or clipping bug in the map display) the game appears to be fully working. Changed description to 'Crackdown (US, FD1094 317-0058-04d)'.

- 0.79: Added 3rd button.

- 0.78: Olivier Galibert added Crackdown (Sega 1989). All encrypted.

History


Sega System 24 disk. published 30 years ago:

Crack Down (c) 1989 Sega.

A futuristic city has been over-taken by a powerful, bio-mechanical army; created by an evil scientist in a bid to take over the world. 2 elite agents must plant a series of time bombs to destroy their base and crush the rebellion.

The 1- or 2-player shoot-em-up action is displayed via an innovative split screen that allows 2 players to work either individually or as a team. A timer countdown timers adds to the tension. Time bombs must be set by running over areas marked with an 'X'; while machine guns and cannons can be reloaded by finding the ammo caches that appear on each level. If ammo runs out, players must result to punching and kicking to defeat opponents.

- TRIVIA -

Released in April 1989.

There is a reference to the arcade game "Shinobi" : the 'Hiyaaa' sound that Ben and Andy exclaim after detonating a superbomb is the same sound as the Shinobi ninja magic sound. Also, 2 of the 4 superbombs also appear in Shinobi. Look closely, the electricity bomb and the whirlwind with homing sickles bomb are here too.

At the end of scene 2 act. 2. There is a machine that produces electrical sparks. On top of the machine can be read : 's-4635 system24'. This is a reference to the arcade board this game runs on.

- UPDATES -

The US version is slightly different, it has the "Winners Don't Use Drugs" screen.
