Version Differences

Version 1.0 was only released in Japan as part of a Special Link Bundle, and is estimated to have sold around 25,000 copies. Version 1.1, used for the rest of the print run and released internationally, contains the more widely-recognized A-TYPE music and is overall a slightly more polished game.
