Super Dog Booby: Akachan Daibouken no Maki [NES – Cancelled]

Super Dog Booby: Akachan Daibouken no Maki (translated by mrdomino as Super Dog Booby: Baby Adventure Volume), is a cancelled platform / action game that was in development in 1990 / 1991 by Jaleco / Taito for the Famicom / NES. Some scans and info were posted in a japanese website, from which it seems that the game was also shown in a playable form at a gaming event in 1991 and it was also offered as a prize in a contest by a japanese magazine. In the end Super Dog Booby was never released for unknown reasons.

Exerion 2 (II) [NES – Unreleased in USA]

The original Exerion was a vertical shoot ’em up released by Jaleco in 1983 and licensed to Taito for distribution on the United States. The game featured parallax effects and inertia simulation, something notable for 1983. [Info from Wikipedia] Sometime later, Jaleco worked on a “sequel” of the game, but as we can read on the Lost Levels forum, it was just the first Exerion with “updated graphics and music”. Anyway, in the end Exerion 2 was never released in America but a prototype was found and leaked online by the Nintendo Age community in June 2009. For all the NES collectors out there, a reproduction cart with Exerion 1+2 can also be bought and played on a real NES thanks to RetroZone!

Ninja Jajamaru-Kun [DS – Cancelled]

Ninja Jajamaru-Kun: Pen wa Ken Yorimo Kyoushidegozaru was going to be a DS remake of the original action game with the same name that was released in Japan in 1985 by Jaleco for the Famicom (NES).  It seems that something went wrong during the development of the DS remake and it was cancelled as reported in Famitsu. Jaleco was then closed down because of “increasing competition in recent years in the video game market”.


Carrier 2: The Next Mutation [PS2 – Cancelled]

Carrier is a cult-classic survival-horror game developed for the Dreamcast. Many fans  wanted a sequel to this game. A sequel, called Carrier: The Next Mutation was being developed  for the Playstation 2. The game, being developed by Jaleco, was sadly never released. Jaleco was  known for the popular arcade series, Bases Loaded.  Like many survival- horror games at the time, Carrier had tank controls, and limited  supplies found throughout the game. The game also used prerendered backgrounds to spice up  gameplay. The game also supplied your character with a pair of special goggles: these goggles  would be used to identify NPCs. The story was similar to many survival- horror games at the time: it would follow two government agents inspecting an aircraft that got disconnecting from  the mainland.  This game was going to be released in early 2001. Sadly, how much of the game that  was completed was never official stated. Even though the predecessor had a place in many fans  hearts, it would overshadow by games such as Resident Evil at the time. This is the reason many  fans believe why this game was sadly cancelled.  We can say that Jaleco is now a dead company, the company was considered  inactive since 2013. A name changed for the company occurred in 2006, and mostly produced  japanese cellphone games. While looking around, it seems Jaleco was delisted from JASDAQ  Securites in 2013. Also, the parent company went bankrupt in 2014.
