Hello. This game does not contain any full-motion video, the disc content is mostly audio tracks, while the game itself only occupies about 30 MB of space. Menu animations are stored in AFM containers (GO2MENU, MENU-D, MENU-M, MENU-U), which contain a series of frame records: the first frame is usually a complete 320×200 image, and subsequent frames record "delta" data, instructing the engine to make local changes to the canvas. This method achieves smooth animation effects while maintaining a small file size because only one full size image is required and the delta frames telling the engine what to change are small. To answer your question, I wrote a small script that can reproduce these changes and save each frame's result as a PNG image, this allows you to reconstruct it into a complete animation that is consistent with the game.

Are these extracted frames from an FMV or are they really stored as individual sprites
