Bugs:

- Language DIP Switch not changing the language. scoobydude51 (ID 05360)


WIP:

- 0.153: Derive (fake) refresh rate from CPU IRQ frequency to reduce juddering [Alex Jackson]. Changed VSync to 41.015625 Hz.

- 0.149: Modernized the MathBox device [Osso].

- 0.133u5: Couriersud fixed invalid DISCRETE_ADJUSTMENT_TAG in Bradley Trainer.

- 0.133u4: Bradley Trainer discrete sound & discrete sound additions [Couriersud]: Added discrete sound. Engine frequency (resistor R11) can be changed with slider. Discrete sound may be disabled by setting BZONE_DISCRETE to 0 in bzone.h.

- 0.129u4: Changed 'Custom' sound to 'Battlezone Engine'.

- 0.117: R. Belmont added save state support to Bradley Trainer.

- 0.115u1: Mathis Rosenhauer moved Atari vector PROMs into separate regions. Added user2 rom (036174.01) and the user3 Mathbox PROMs (36175/76, 036177/78, 036179/80 - low/high nibbled). Changed region proms to user1.

- 0.108u5: Mathis Rosenhauer rewrote the Atari vector generators, using the schematics and actual state machine PROMs. The state machine is now emulated so timing should be much more realistic. Clipping hardware in bzone and others is emulated instead of hardcoded. Improved accuracy of clocks and various other bits of cleanup. Changed M6502 CPU and POKEY sound clock speeds to 1512000 Hz. Added prom ($0 - AVG PROM).

- 0.74u2: Removed the shell firing range hack, now uses IPT_AD_STICK_Z. Removed 2nd Player.

- 0.62: Aaron Giles added 'Bradley Trainer' (Atari 1980).

- 0.58: Aaron Giles added (Testdriver) Bradley Trainer.

- 15th January 2002: Aaron Giles added a preliminary Bradley Trainer driver, however the controls and colors are not correct.

History


Arcade Video game published 38 years ago:

Bradley Trainer (c) 1981 Atari.

The gameplay is very much a simulation. The other tanks do not fire at you, and the only way to end the game is to run out of ammo or shoot a 'friendly' tank or helicopter.

- TECHNICAL -

Main CPU : MOS Technology M6502 (@ 1.512 Mhz)
Sound Chips : POKEY (@ 1.512 Mhz), Custom (@ 1.512 Mhz)

- TRIVIA -

In December of 1980, a group of consultants from the US Army approached Atari with the idea that the game "Battlezone" could be made into a simulator for the then-new 'IFV' Infantry Fighting Vehicle (or the Bradley Fighting Vehicle, as it is known now).

Many physical and gameplay changes were made to the original game, such as a new control yoke (a similar control was used for Star Wars), friendly and hostile vehicles and helicopters, more weapons (7.62 mm machine gun, a cannon with armor piercing or high-explosive shells; and a tube-launched optically-guided missile launcher, or TOW), and view selection (normal or magnified). The key was to guess the size of the target, use the on-screen gauge to align it, and dial in the distance to the object, to hit it with the first shot.

A prototype of the simulator was rushed out in March 1981, and was introduced at the worldwide TRADOC conference that year. It was a hit at the conference.

Ed Rotberg, the project programmer, was very opposed to doing the project, mainly due to the principles of such a project. He felt that technology used to produce Battlezone and video games in general shouldn't be used for bad purposes, such as weapons research, and cited the conversion of automobile factories into tank and airplane factories in World War II. Rotberg spent two months on the project, and resented it the entire time.
