The limited edition of the Japanese version of Apollo Justice: Ace Attorney came bundled with Gyakuten Saiban Jiten, an interactive encyclopedia that allows players to read about the contents of the first three games, view character sprites, and play music from the games. When asked in 2009 if it would ever be localized in languages in other than Japanese, series product marketing manager Colin Ferris stated that they were looking into ways to bring it to North America, but these plans never came to fruition.
