This game is known in Japan as "The Undoukai" (translated from Japanese as 'The Athletic Meet').

When playing against the computer, it's uses the abbreviation Z80 - which refers to the processor on the PCB board.

The game is clearly related to Konami's "Circus Charlie", "Track & Field" and "Hyper Sports" games, sharing many identical graphical items, yet was released by Taito. The tilemaps contain the same type of 'bonus' graphics, but it is unknown how they are triggered.

Information on fieldday

0.69u3 [Tomasz Slanina]

0.57 [Uki]

< Japan >


- 0.140u2: Atari Ace take some driver_device classes of 40love/bking/buggychl/msisaac (common code in machine\buggychl.c) that cover multiple drivers and split them so that each driver gets their own driver_device class. In most cases, these drivers got entangled because of audio/mcu code that was shared between multiple drivers.

- 0.140: Angelo Salese removed deprecat.h usage from Forty-Love driver.

- 0.135u3: Fabio Priuli added shared driver data struct to Forty-Love driver.

- 0.129: MooglyGuy added savestate support to Field Day and clone.

- 0.127u4: MASH fixed a source typo in the 40love driver of MAME 0.126u2 (Field Day and clone Undoukai doesn't start).

- 0.124u5: Roberto Zandona fixed small graphics corruption in Field Day and clone.

- 0.123u6: RansAckeR added use of PORT_DIPUNKNOWN_DIPLOC and use of PORT_INCLUDE in Field Day.

- 0.119u1: Pierpaolo Prazzoli fixed regression in clone 'The Undoukai' caused by the REGION_CPU1 decoupling from RAM.

- 0.100u4: Aaron Giles converted Forty-Love driver driver over to using the new memory_configure_bank calls.

- 0.69u3: Tomasz Slanina added Field Day (Taito 1984).

- 4th June 2003: Tomasz Slanina added Field Day, the world version of Undoukai, to the Forty-Love driver.

- 7th December 2001: Uki added The Undoukai to the Forty-Love driver.
