Burger Time (Data East set 1)

0.35 [Nicola Salmoria]

0.11 [Mirko Buffoni, Kevin Brisley, Nicola Salmoria]


TEST MODE:

- In test mode, press 5 to advance through the various tests.


NOTE:

- The indicator that shows how many chefs you have remaining is broken, so keep a careful count for yourself. This is probably due to a bug in the original Burger Time ROMs.

- Clone cookrace: A high-pitched whine is heard throughout the game. A flaw in the original game. Most likely the arcade units have either a low-pass filter or such lo-fi speakers/amplifiers that you wouldn't hear it.


WIP:

- 0.101u3: Fixed cpu2 rom address in clone Cook Race.

- 0.97u1: ShimaPong fixed input in clone Cook Race.

- 18th August 2001: Zsolt Vasvari updated the 6502 CPU core so that another hack could be removed from the Burger Time decryption.

- 31st January 2001: Juergen Buchmueller further fixed the i8x41 core and hooked some parts of the DECO cassette system to the Burger Time driver.

- 8th July 1999: Zsolt Vasvari fixed Burger Time sprite placement in cocktail mode.

- 0.35fix: Renamed (btime) to (btimem).

- 0.35: Burger Time (Data East set 1) is original now. Renamed (btimed) to (btime).

- 5th March 1999: Aaron Giles has fixed more drivers to work with rotation handling (galaga, frogger, burger time and their clones).

- 0.35b2: Added cpu1 rom (32bytes - reset/interrupt vectors) and prom ($20 - unknown) to Cook Race.

- 0.35b1: Nicola Salmoria added clone Burger Time (Data East set 1). Renamed (btimea) to (btimed2). Version (set 1) is a different ROM set, without Midway copyright and different attract mode. Version (set 2) is the same as (set 1), but with two instructions NOPed out (function unknown). Cook Race is a bootleg of the cassette version (different hardware and different gameplay).

- 0.34RC1: Nicola Salmoria changed description of clone 'Hamburger' to 'Cook Race'. Cook Race is running on different hardware and with levels in different order.

- 0.33b7: Martin Sandiford added Cocktail mode support.

- 0.33b3: Zsolt Vasvari added proper emulation of the ROM decryption in Burger Time.

- 0.31: Added clone Hamburger. Game doesn't work and the roms seem to be encrypted.

- 0.29: Nicola Salmoria fixed Burger Time: Lives left are correctly displayed, sprites are turned off appropriately, and the switch test in test mode works correctly. The hardware of this game is more similar to Eggs.

- 0.23: Some fix to Burger Time sound pitch.

- 0.16: Various fixes to Burger Time: Fixed CPU clock speed to avoid slowdowns on fourth level. It's much faster on a 486. Sprites no longer "stick" on the screen on a level change. Fixed a bug in high score save. Fixed a couple of bugs in M6502 BCD arithmetic. One of them was causing the pepper counter in Burger Time to behave strangely.

- 0.15: Hiscore save in Burger Time.

- 0.13: Added Burger Time (Data East), which is likely an earlier version. Fixed all of the problems in Burger Time related to ROM encryption. Slices fall more than one level when an enemy is on them, no more crashes when a bonus life is earned, the high screen table works, two players mode works, and other things.

- 0.12: Sound support in Burger Time. This is the first multiple CPU game supported by MAME (two 6502, one for code, one for sound). It's not perfect, but we're getting there. Fixed speed in Burger Time (was running at about half the real speed). A similar change to the 6502 engine, it was needed by Burger Time which wouldn't accept coins otherwise.

- 0.11: Mirko Buffoni provided a driver for Burger Time (Midway 1982). The colors for Burger Time should be accurate. There are the same problems with ROM encryption that Replay 0.01a by Kevin Brisley has.
