Apple II
Developed by Datasoft and published in 1985.
Atari 2600
Developed by Coleco and published in 1983. The most primitive of all home conversions. Cherries are arranged in groups of two by three (as opposed to two by four) and digging along an adjacent column or row leaves no barrier between either one, making it easier for enemies to catch you if you snake back and forth.
Atari 400/800/XL/XE
Developed by Datasoft and published in 1984.
ColecoVision
Developed by Coleco and published in 1983.
Commodore 64
Developed by Datasoft and published in 1985.
Game Boy
Developed by Ocean and published in 1990. Contains an original version, and a remixed version. In the remixed version, the following changes occur: There are more monsters then there are allowed on the screen at a time, diggers travel faster and morph into monsters slower, the bonus foods are different, the diamond moves, and the music is different.
MSX
Converted for play on the MSX by Angel and published in 1984.
SNES
Developed by Imagineer and published in 1995. An extremely accurate conversion with the only changes made to the location of the score and status by moving them to the right side of the screen.
X68000
Ported to the Sharp X68000 computer system in 1994 by Dempa/Micomsoft as volume 10 of the Video Game Anthology series. A pixel perfect conversion.
Noteworthy
Atari 400/800/XL/XE
Developed by Rita Jay and published by Microdeal in 1984. While cruder in detail and digging resolution, (and even though the monsters were changed to gunmen), many of the details about the game play, and the music that is played is identical to Mr. Do!.
Commodore 64
Developed by Rita Jay and published by Microdeal in 1984. Nearly identical to the Atari version described above.
TRS-80 Color Computer
While this version of the game was published by Microdeal, the copyright screen says Computerware. It is unknown if this Mr. Dig is related to the two listed above, as it is far more indentical in look and spirit to the original Mr. Do! than the other versions. However, this may be because the TRS-80 did not receive an official conversion of Mr. Do! while the other two systems did.
