Cabal, TAD Corporation's first game, managed to establish a new genre of action games and be a pretty fun game in its own right.

Demo Recorder

There's a demo recorder that's enabled if ROM address 0x3FFF0 is set to 0000: It's set to FFFF in commercial sets. Place the following code in MAME's cabal.xml cheat file (or the cheat file for the Cabal set of your choice) to re-enable the demo recorder.

The game will try to write both player's inputs and the current RNG value to the main board, but since the commercial boards are read-only it doesn't quite work. Pressing 1P Start will (try to) write FFFF to the ROM to mark the end of the demo; After that, the game goes into an infinite loop to prevent further recording.

Developer Credits

Found in 0x0F00 in the audio CPU:

 Michel/Seibu   
 sound 11/04/88

"Seibu" probably refers to Seibu Kaihatsu, which would go on to release Dynamite Duke, a shooter with gameplay very similar to Cabal, in 1989.

Removed Level

Six levels were designed for Cabal, but an entire level was dummied out before release. Put the following cheat code in MAME's cabal.xml cheat file and enable it to replace Level-1 with this unused level.

Screen 1	Screen 2	Screen 3	Screen 4

Though the level intro screen says this is Level-5, the internal order of the game's levels suggests that this was supposed to be Level-1. Perhaps they were debating on which of the levels would end up as Level-5 and which one would be cut.

Unfortunately, only the screen and tilemap data remain in the ROM. There's no object data for any of the four screens, nor do there seem to be any sprites in the object graphics ROM that match up with the buildings shown in the level intro.

Unused Graphics

The levels in Cabal were originally called scenes. This graphic was apparently around before the sixth level was cut from the game.

An unused power-up that would give the player an extra life (which are represented by hearts in the game).

Used	Intended

The monolith in Level 1-2 seems to have accidentally been assigned the wrong palette number, 06. The correct palette number, 0C, makes the message on the monolith legible.

Region Differences

The Japanese, North American, and European releases use trackball controls. The nebulous "World" set uses a joystick instead.

Revision Differences

There are at least two US revisions of Cabal. The newer revision -- cabalus in MAME -- was produced sometime after January 1989, so the now mandatory "Winners Don't Use Drugs" screen was added to the game's attract mode.
