DJ Boy

DJ Boy skates across various stages and utilizes hand-to-hand combat moves in order to defeat opponents, culminating with a battle with a boss at the end of each level. Along the path, the player also encounters prizes, which then can be used later to purchase Power-ups from a store located at the end of each level (in the home version, the arcade simply tallied these as points). In the console versions of the game, as another game, River City Ransom, the "prizes" consist of coins that are dropped by defeated enemies, or food items like burgers that restore health.

The premise of the home console game: A young man named Donald J. Boy (DJ Boy) is a roller fighter taking part of an ultimate fight-race known as "Rollergame", taking place in Cigaretch City, located on the outskirts of New York City. Many people were excited to see DJ Boy, but a roller fighter gang known as the Dark Knights want him out of the competition. Their leader, Heavy-Met Tony, calls his gang to kidnap his girlfriend Maria, who also comes into town and defeat DJ Boy.

DJ Boy must rescue Maria, defeat the Dark Knights, and win the Rollergame competition in one adventure. The arcade plot tells a different story. Two rollerskaters named Bob & Tom (the two playable characters) were breakdancing to the beat of their boombox, until it got stolen from rollerskater thieves (possibly the Dark Knights), in which they must find and defeat them in order to retrieve what is rightfully theirs.

In Japan, Game Machine listed DJ Boy on their October 15, 1989 issue as being the seventh most-successful table arcade unit of the month. In North America, it was the top-grossing software conversion kit on the RePlay arcade charts in May 1990. Entertainment Weekly compared the US release to the Japanese version, and wrote that "D.J. Boy still does battle with an enormous black woman, only here she's a few shades lighter and no longer has a fondness for flatulence. Kaneko USA: '[The Japanese programmers] were looking for input, and obviously they got it from the wrong people.'"

The Mega Drive version received mixed reviews. MegaTech magazine gave a 78% review score, praising the game being fun to play although giving criticism that the game being too easy. Sega Power magazine gave the game an overall 30% score, criticizing the boring gameplay, the levels being too easy, the dull graphics, terrible sound and concluding "A nob beat-em-up with added nobby bits. The levels are dull, the moves limited and the end-of-level bosses too tough to beat.

In 1992, a sequel, B.Rap Boys (Bラップボーイズ), was produced containing similar designs and content. The game features three player simultaneous action using characters that are different from one another (rather than palette swaps), and the optional use of weapons and vehicles, as well as a more robust fighting system. The game's soundtrack was notable for having extensively sampled studio recordings from the long former hip-hop group 3 Stories High. In Japan, Game Machine listed B.Rap Boys on their August 1, 1992 issue as being the thirteenth most-successful table arcade unit of the month.
