Joe & Mac,^[a] also known as Caveman Ninja and Caveman Ninja: Joe & Mac,^[1] is a 1991 platform game released for arcades by Data East.^[2] It was later adapted for the Super NES, Mega Drive/Genesis, Nintendo Entertainment System, Game Boy, Amiga, Zeebo, Nintendo Switch, and PC.

Gameplay – Joe & Mac

The game stars the green-haired Joe and the blue-haired Mac, cavemen who battle through numerous prehistoric levels using weapons such as boomerangs, bones, fire, flints, electricity, stone wheels, and clubs. The objective of the game is to rescue a group of women who were kidnapped by a rival tribe of cavemen. The game features a health system by which the player loses health over a period of time, apart from during boss battles.^[3] A two-player mode is available, and in some versions both characters are capable of damaging each other.

The original arcade version and Amiga, Mega Drive/Genesis, MS-DOS and Zeebo ports have the distinction of allowing the player to select between different routes at the end of boss battles. Also, after defeating the final boss, the players can choose between three exits – each one leading to a slightly different ending sequence.

Ports – Joe & Mac

The game has been ported to various systems, some of which drop the name Caveman Ninja, referring to the game simply as Joe & Mac.

A Super NES version was developed and published in 1991 by Data East.^[4] In December 1992, a version for the NES was released. It was developed by Elite Systems and published by Data East.^[5] A Game Boy version, released in North America and the United Kingdom in April 1993,^[6][7] was developed by Motivetime and was also published by Data East.^[8] 

Finally, in late 1993, another version was developed by Eden Entertainment Software and published by Takara for the Sega Genesis and TecToy for the Brazilian Mega Drive in early 1994.^[9]

The Mega Drive/Genesis version is considered a close match to the arcade version.^[10] The Super NES version is a reworked game which features an overworld map used to choose the levels (unlike in other versions where all of them have to be played), which were longer, plus some bonus stages (either in the levels or out in the world map). Some of the weapons are missing and can no longer be charged up.

The final boss is also different, and there are only two endings. The NES and Game Boy versions lack the option of choosing levels or endings. Both feature variants of the arcade boss.
