1991 (unreleased)[]

Sonic Edusoft was an educational game developed by Tiertex in 1991. Originally set to be released for Sega Master System by Sega and U.S. Gold, the game was cancelled and remained unknown from the public until a now-deleted page of the game was published in Wikipedia with the game's programmer stepping in and sharing information about the game's history.[1]
While no logo exists, the game ROM released online on April 27th, 2008, consists of a title screen.
