Dezaemon Plus is a 2D vertical-scrolling shoot-'em-up construction kit developed and published by Athena for the Sony PlayStation exclusively in Japan on May 24, 1996.
The third entry in the Dezaemon series, Dezaemon Plus is an enhanced version of the Super Famicom entry in the series. Along with numerous minor improvements for the PS1's 32-bit architecture, the game is also the first to allow players to save their custom content to an external memory source (PlayStation memory cards) for storage and transfer. Along with an improved version of the Daioh Gale sample game (titled Daioh Gale rev. 2), the game also includes two hidden sample games: the original Daioh Gale and Omake Power Storm.
Due to the game's ability to save to an external source, Athena ran a competition where players submit their custom games in memory cards. The top ten winners (as well as 92 other entries) were later bundled as a bonus disc for Dezaemon Kids! (titled Dezaemon Select 100).
It was later digitally re-released for the PlayStation Network in Japan (on January 30, 2008), North America (on November 30, 2010), and Europe (on November 9, 2011). The overseas versions were released by MonkeyPaw and are untranslated (requiring use of their online translation guide), while none of the PSN versions have mouse support.
