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”.
