FlickBook is an animation toy for the Nintendo DS. It allows you to create an animated film by drawing a series of frames. FlickBook requires a DLDI device with write support, so patch in the normal way.

Changes:

– Up to four layers.
– Fixed layers keep the same image for all frames.
– Normal layers can change from frame to frame.
