During development, the animation set for one of the character models was almost lost. One of the developers was able to extract the animations using a program named Umodel.

In the PC Version, when creating a Series EV Hero, five of the possible default names for the hero will be "MegaGirl", "ProtoGirl", "Roll", "Rush", and "Beat", all of which are references to Mega Man characters.

In addition, a default name for the Jester is "Nights", a reference to the titular character of "Nights Into Dreams", whom the Jester bares a resemblance to.
