Version Differences#

To do: there's more than this.

The game was originally released for the DECO Cassette System, Data East's interchangeable arcade system board. Since arcade owners complained about the potential unreliability of both the tapes (which could be demagnetized easily) and key modules (which EPROMs went bad after a time) of the DECO Cassette System, later Data East released BurgerTime on a standard dedicated board.

Five distinct versions are present in MAME:

• chamburger is the original Japanese version that runs on the DECO Casette System.
• cbtime is the original North American version that runs on the DECO Casette System.
• btime is the second Japanese version version that runs on the standalone Data East's Lock 'n' Chase hardware.
• btime3 is an initial second North American version handheld by Data East themselves that runs on the standalone Data East's Lock 'n' Chase hardware.
• chamburger is the most common second North American version licensed by Bally Midway that runs on the standalone Data East's Lock 'n' Chase hardware.

Title Screen#

Japan (DECO Casette System)	US (DECO Cassette System)	Japan (Standalone)	US (Standalone, Data East)	US (Standalone, Bally Midway)

The game was originally called Hamburger in Japan. To avoid potential trademark issues, the game title was changed with the more iconic BurgerTime in North America. The latter title was used for all standalone versions, although the standalone Japanese version incorrectly uses a spacing.

Both Japanese versions features Data East's classic logo, while the North American versions have a more standard copyright string for Data East/Midway in its place.
