Darkman was developed by Twilight and published by Ocean Software in 1991. It was released for the ZX Spectrum, NES, Amstrad CPC and Commodore 64.[1] It was also ported to the Game Boy and Atari ST.[2] The game's plot is loosely based on the film of the same name. In this side-scrolling platformer, the player controls Darkman, a superhero who can jump, kick and punch, as well as swing from a rope during action sequences between levels. In each level, Darkman disguises himself as the boss of the level, whom he must defeat before the time limit elapses. Tying into the plot of the film, Darkman wears masks of various gangsters who are responsible for his disfigurement, but his disguise dissolves after being exposed to sunlight for too long. The character changes into a different member of the evil gang in each level, taking on their attack moves as well as their face. In-between levels, Darkman must photograph his quarry before he can make a mask of them. These scenes involve moving the cursor to take a picture of the gangster. The better the photo accuracy, the more time Darkman is granted to complete the subsequent level. The final level is the most faithful to the film, and takes place on a skyscraper under construction. After the player defeats their mirror image five times and wipes out the mob cartel that scarred Darkman, the final boss is inexplicably a clone of Darkman himself.

Dash Galaxy in the Alien Asylum was an action game for the Nintendo Entertainment System released in 1990 exclusively in North America. Players take the role of Dash Galaxy, a space scout who has been captured by a hostile civilization. Gameplay involves a series of floors with several rooms each. Keys must be collected to progress to higher floors, and eventually, an escape ship. Dash's only weapons are a limited supply of bombs and remote detonators. Good timing is crucial to completing the game, requiring navigation of trampoline jumps and roaming enemies. While the rooms are side-scrolling action puzzles, the floors have an overhead view, and include more difficult block-moving puzzles which can fatally trap a player.

The Datach (データック, Dētakku) or Datach Joint ROM System, was an add-on accessory by Bandai for the Family Computer and was released on December 29, 1992. It was packaged with one game, Dragon Ball Z: Gekitō Tenkaichi Budokai. Six other games that were released for it, including one of the last games for the Famicom system in 1994. It is one of two mini systems compatible with the NES/Famicom, the other being the Aladdin Deck Enhancer. The Datach consists of a cartridge connection at its bottom, a central cartridge chamber on its back, with two spring-loaded pins on either side, which are pushed up when the unit is inserted into the Famicom, allowing the game to only be removed when the Datach has been removed from the Famicom. Its main feature is the card reading slot on the front. The cartridges resemble half-size Famicom cartridges. One side of the cartridge is flat with title sticker, while the other side is sloped inward with notches on the left and right, which correspond to the spring pins on the main Datach unit. The cards that come with the games are swiped from left to right along the card slot; they are glossy on the front with an image of the character and the backs are smooth usually having the title of the game and barcode. All cartridges, boxes, instructions have the standard FF (Famicom Family) insignia, showing they are officially licensed by Nintendo.
