Spin Master, known in Japan as Miracle Adventure (ミラクルアドベンチャー), is an arcade game developed and released by Data East in December, 1993 in North America, in Europe the same year and on February 18, 1994 in Japan. It is the first game Data East developed and released for the SNK Neo-Geo MVS hardware. Its plot and setting are identical to Data East's SEGA Genesis / Mega Drive game titled Dashin' Desperados; however, aside from the two lead character designs, the rest of both games are completely different. In fact, they are so different that Will, Rick, and Jenny go by Tom, Johnny, and Mary in Spin Master. Also, Spin Master's gameplay, artwork style, animations of some characters and the styles of its weapons were heavily inspired by another arcade game by Data East titled Joe & Mac, according to the Japanese Miracle Adventure arcade flyer.
Many years ago, a large treasure was hidden by a mysterious guy on an uncharted island. The guy of mystery drew the location of the treasure on a map and hid it deep in the forest of the island. Days turned to weeks, weeks turned to years, and years turned to decades. The guy who hid the map disappeared, never to be seen again. During this time, the map became dirty and weathered, eventually tearing into five pieces which were scattered about the corners of the world. One of these pieces wafted its way into the possession of the young treasure seeker name Johnny. Living with his girlfriend Mary and his rugged sidekick name Tom, Johnny dreamed of the day when he would some day find the ancient treasure on the hidden island of the mysterious guy.
Then one day, the greedy, treasure-seeking mad scientist, Dr. De Playne appeared in Johnny's little town. Seizing Johnny's piece of the treasure map and kidnapping Mary, Dr. De Playne set out to find the treasure and buy up all the toys and candy of the world, plunging the children of earth into a bitter darkness of continuous study and well-balanced meals. Johnny and Tom pursued the mad Dr. De Playne with their yo-yos to save Mary and the world.
In this game, Player One controlling Johnny (one with blond hair) and Player Two controlling Tom (one with cowboy hat) will begin in a mistakenly-named location: Madrid, Spain in one of the Americas (which is actually in Europe). Johnny and Tom will both be armed with yo-yos to hit enemies and treasure chests that contain better weapons like throwing stars, icicle daggers and guided missiles. Other moves they can perform are slide tackles and use special extreme attacks that defeats every minor enemy and seriously damages bosses on screen. In addition, they can spirit charge their normal yo-yo attack by holding down the button until charged; however the spirit charge isn't very effective in comparison to the regular shot.
