The game's Japanese release made use of the Game Boy Advance E-Reader, but the feature was removed in the international release due to the lack of the device's popularity. In the Japanese release, the Request BBS required the use of E-cards and it was possible to obtain Gregar and Falzar battle chips. In the international release, not only is it impossible to obtain these without hacking, but they were broken, causing them to crash the game if used.
