Mottomo Abunai Deka (もっともあぶない刑事 = The Most Dangerous Detectives) is an action-platformer released in Japan in 1990. The game was published by Toei Animation and developed by the infamous developer Micronics. The game is based on the Japanese television buddy-cop series Abunai Deka.

In the game, the player can choose to play as either of the two main characters; Toshiki "Taka" Takayama, or Yūji Ōshita. Alternatively, a two-player co-op mode is available where player 1 and 2 control Toshiki and Yūji respectively. The game plays similar to Namco's Rolling Thunder (ARC); even the player character's animations are similar. Also like Rolling Thunder, you start with a pistol but can collect an SMG with limited ammo, and can jump down from higher ground to lower ground. There are 12 stages in all. Most of them are traditional action levels where you must get from point A to point B. However, there's a couple first-person shooting stages, as well as one driving stage.

While the game was never released outside of Japan, hackers fan translated the game, and a ROM can be found online. Being that the game was from Micronics, it was heavily criticized for being plagued with the problems Micronics games were known to possess, such as the gameplay being slowed down from too many objects on the screen, awful graphics, stiff controls, and dull gameplay. As a result, many Japanese players have called the game kusoge (shitty game). If you like easy games regardless of how bad they are, then it may be good to know that the entire game can be beaten in around 20-30 minutes.

The game shamelessly rips off another Konami game, Road Fighter.

Mottomo Abunai Deka features music by Kimio Nomura, who seemed to be tied with Toei Animation at the time, and received only two known game credits, the other being SWAT: Special Weapons and Tactics (FC). There are ten songs, which was the average amount for an action game at the time. Most of the music is moderate to fast-paced rock.

Most stages in the game share the same theme, but a couple are different; this is when you are playing the driving level, as well as the final stage inside the Police Station.

The game suffers the same fate as a lot of other Micronics games at the time, in that their audio driver makes the music sound less pleasing to the ear than it could be, and there are really high frequencies played as well, which can be grating. Also, besides the title and ending music, none of the songs in the game use the noise channel for percussion.

The game's credits are displayed upon completion of the game. More than likely, a programmer at Micronics converted Nomura's composition to code. However, the game does not credit an arranger, so it is unknown who did the conversion, but it was likely Kazuo Yagi, who also programmed the game. This is also supported by the game sharing sound effects from other Micronics games such as Zoids II: Zenebasu no Gyakushuu, which also credits Yagi as the programmer.

Ripping NES music is a very arduous process that is beyond the scope of this site.
