The game takes place in Chicago during December 1941, shortly after the attack on Pearl Harbor. The player awakes one morning in a bathroom stall, unable to remember who he is. The bathroom stall turns out to be in Joe's Bar. A dead man is found in an upstairs office, and Ace is about to be framed for the murder. There are some clues as to the identity of the murdered man and to the player himself.

The streets of early 1940s Chicago are an unsafe place for a man with no memory. There are muggers, an old acquaintance with a grudge, not to mention the police. Here, the player's history as a boxer is a much more valuable asset than the smoking gun picked up in the game's beginning. Using addresses found around Joe's bar, Ace is able to make taxi rides to a few locations, including his office. A story unravels of a kidnapping in which Ace has played some part, but his memory lacks important details.

Ace's memory and mental condition get progressively worse, but eventually he is able to obtain an antidote to the drug that caused the memory loss. His recurring flashbacks now become filled with information. The police are still on his back, but with this new information the player is better able to evaluate the evidence and take action accordingly.

     Solomon's Key is generally recognized as one of the most difficult games to appear on the NES. The player must overcome unlimited enemy spawning, challenging level designs, a countdown timer, Dana's fragility, and limited ways to dispatch enemies. In addition, it's easy for players to unintentionally make levels impossible to clear while playing them.

     The main character, Dana is sent to retrieve "Solomon's Key" to restore the world to light from demons that were accidentally released. The object of the game is to advance through the 50 rooms of "Constellation Space" by acquiring a key to the door that leads to the next room before a timer runs out. The game incorporates elements of the platform shooter genre. Dana can run, jump, create or destroy orange blocks adjacent to him as well as create fireballs to destroy demons. The orange blocks can also be destroyed by hitting them with your head twice. Along the way Dana can acquire items to upgrade his firepower and extra lives as well as items that award bonus points and unlock hidden rooms. With certain items, Dana must make, then break blocks (sometimes in a certain manner) to make these appear.

     Dragon Power is actually a Dragon Ball game from the Harmony Gold USA era (although their input was limited at best) It stars Son Goku and very roughly follows the first two volumes of the Dragon Ball manga, often called the Emperor Pilaf Saga. The game consists of 2D overhead areas where Goku must fight many enemies and side scrolling sequences for the boss fights. This was notably the only Dragon Ball-related game to be released in the US for the NES.

     Although the Japanese and European editions of the game used the familiar art and music from the Dragon Ball anime, the US edition made several graphical and translation changes to make the game more easily understood by the audience as the series would not be dubbed into English, at least not on a widespread basis, for another ten years. Goku now more closely resembles an Americanized Kung Fu stereotype and is pictured on the box with a white gi (instead of his traditional orange which he wears in the game itself) and blue headband. In the game, he has been modified to look more like a monkey. Muten-Rôshi, similarly has been changed to look more like a traditional martial arts master. Despite these cosmetic changes, the game is still very recognizably a Dragon Ball game and all other plot elements (the search for the Dragon Balls, etc.) remain the same.

     Toad, the player's avatar in the game, has to arrange monsters and bombs to stop Wario from taking control of the forest. The player controls a character who moves the already fallen objects. Toad can pick up individual objects or entire columns of objects and move them elsewhere. The object of the game is to clear the player's screen of objects, the objects of this game being the monsters. This is accomplished by arranging monsters and bombs of the same color in horizontal, diagonal or vertical rows of three or more blocks. Clearing four objects at once lowers your opponent's screen by one row in Vs. mode, or gives you more time in single-player mode.
     The version of Wario's Woods for the Nintendo Entertainment System had fewer features than its SNES and Satellaview counterparts. Besides the obvious graphical disparity, the game has no "vs. Com" similar to the Super NES version. The soundtrack of the NES version also differs from the other releases. The only computer AI mode is a game in which every ten rounds the player has to fight a boss. The boss has a certain amount of hearts that can only be reduced by clearing lines in which the boss is inline with. Once all of the boss's hearts are gone the player can continue onto the next round. These boss fights culminate in a fight against Wario himself.
     This is the only game in the NES library to receive an ESRB rating, and was the last officially licensed game to be released for the system in North America.

     In 2030, prosthetic limb technology has advanced to the point that prosthetic limbs can be every bit as accurate as the real thing. A team of scientists have been assigned to create military uses for these new limbs. However, a group of rogue scientists unite with plans to use the technology for world domination, under the name Metal Command. To combat the revolutionary movement, the Law and Order Regulatory Divison is formed.
     They assigned a new group of scientists to develop something to combat Metal Command.
They develop a very special pair of hands. These hands give the recipient the strength of a piledriver. But without a willing recipient, these hands cannot be used.
     Meanwhile, Steve Hermann, a Bronx police officer is chasing down a Metal Command cyborg, when another cyborg sneaks behind him, and the two cyborgs close in, turning Hermann into a human sandwich. They pull apart to see if Hermann is alive, while despite his crushed hands and ribs, Hermann manages to run to his freedom.
     Several days later, after his crushed hands have been amputated, a L.O.R.D official visits Hermann, and offers him the chance to defeat the group responsible for nearly killing him. Hermann accepts the offer, and after two months recovering from injuries, he emerges as Shatterhand, to protect his identity while he takes down Metal Command.

     In the far future, a virus has appeared in the Main Defense Computer of the planet Earth. The origin and nature of the virus is unknown. Scott O'Connor volunteers to undergo an experimental transfer technology that converts his brain into raw binary code. He takes on the image of a Kabuki dancer, since the computer recognizes his grandfather as one. The virus in the virtual world takes on properties of an actual virus-it leaves behind debris, mutant creatures, and parasite environments of a biological nature. At the final level, it is revealed that the virus is of alien origin, having been picked up by a lost Hyperion probe launched to a neighboring planet. O'Conner stops it before the virus can order the Hyperion to fire its laser weapons and destroy the human population.
