Binary Mercury Steam Save Documentation

This wiki provides information on the BMSSV save format used in both Metroid: Dread and Metroid: Samus Returns. Information on data structure, known data types, and other useful information can be found here. Please use the navigation on the right to get started.

NOTE

This wiki will eventually be the home for both formats used in Metroid: Dread and Metroid: Samus Returns. Currently, effort is directed towards information on the Dread format. If you wish to see the wiki for Metroid: Samus Returns, click HERE.
