Intrigued, Taro began to dig deeper. He discovered that Super Robot Taisen BX was a tactical role-playing game developed by B.B. Studio and released in 1995 for the Super Famicom in Japan. The "Rev 1" version, in particular, was a revised edition that contained several changes and improvements over the initial release. According to the forum, only a handful of Rev 1 cartridges were produced before the game was re-released in its final version.
