The Fourth Protocol1985

Based on the board game of the same name, 221 B Baker St. pits up to four players against each other in a race to solve mysteries set in Victorian London. After picking a character (Sherlock Holmes, Dr. Watson, Irene Adler, or Inspector Lestrade), players select one of the thirty available mysteries and read its case file in the game's manual. The case file presents the particulars of the case, mentions the people involved, and explains what the players need to deduce to win the game. Before solving the case, players must visit Scotland Yard for a badge. Players might also want to use a badge to lock a location with a useful clue, requiring other players to detour to the locksmith. Once a player believes they have solved the case, they must return to Baker Street and answer a quiz. If the player is incorrect, the other players can continue.

Based on the Casper film, the game pits you in the role of the friendly ghost trying to make a friend and a second chance at life instead of scaring everyone away.

Casper will need the help of Dr James Harvey - therapist to the dead - if he has any hope of succeeding in his adventures. Casper will also have to deal with his uncles - Stretch, Stinkie and Fatso, who just love to scare "Fleshies" and thwart Casper's efforts. The gameplay is 3d - and is mostly puzzle solving, with Casper able to take a variety of forms and manipulating objects.

Inspector Gadget: Gadget's Crazy Maze isn't the type of game one would expect when taking on the role of the bumbling, multi-functional detective of the 1980's cartoon. Rather than an action title like its Game Boy Color counterpart, this incarnation of Inspector Gadget is best described as a puzzle game with limited action elements. According to the story of Gadget's Crazy Maze, Inspector Gadget's mysterious arch-nemesis is up to no good once again. This time, the MADD ringleader Dr. Claw has been creating mind-control crystals on his secret moon base, then tossing them down to Earth. If the crystals lay dormant for a short amount of time, they will activate, taking control of the consciousness of the whole world. To make sure no one disturbs them, Dr. Claw has spread them all around four different areas and inserted his vile henchmen to protect them.
