The '''section header''' is a very common 20-byte header that denotes different data sections, found in many different Donkey Kong Country: Tropical Freeze formats.
''This article is for the SAVW format from Metroid Prime 1 and 2. See [[SAVW (File Format)]] for the other revisions of this format.''
 
The '''SAVW format''' determines what data gets saved to the memory card. It's used to save information on non-hardcoded parts of the game, like whether a particular MemoryRelay has been activated, whether you've scanned a particular scan has been fully scanned, etc.
