{{todo|Investigate what each of the four unknowns actually controls. The files are 3be96f49.SCAN, fe4e51c7.SCAN, and 1e4b491f.SCAN, though the latter only has non-zero values for the unknowns in the demo.}}

An extremely small number of scans display animated images in Metroid Prime. In the final version of the game, only a terminal in the Map Facility displays an animated image. In the demo version of the game, the aforementioned terminal scan and the Parasite Queen scan both display animated images. For most SCAN files, the last 32 bits of the scan image entry are zeroed out, but for the animated scans, these 32 bits have actual values in them. Strangely, the terminal directly to the left of the animated terminal in the Map Facility also has non-zero values for these 32 bits, even though it does not display any animated images.
