MySims Research

These files try to document MySims (PC) to the best of our ability. And do not document any of MySims sequels or MySims DS.

Interested in making mods? This wiki now also includes information on how to mod the game using the MySims Modloader here.

⚠️ IMPORTANT

These documents are a work in progress.

Patterns

This documentation uses ImHex's HexPattern files, which are an easy way to program and display how binary file formats are defined.

Versions

MySims was released multiple times on different platforms.
