SFS

(This page is a work in progress)

This page is about the KSP Savegame format. Some of this is documented by the KSP Wiki, but apparently only for cosmetic tweaks. The SFS file seems to have some interesting parameters that are not normally exposed in the game, and so it is hopeful that this research is useful even if KSTweak fails. As an example, it appears that one may:

• Forbid the use of any building through the GAME::SPACECENTER::CanGoIn* properties.
• Forbid saving or loading via the Game::EDITOR::Can[Save|Load] properties.
• Name kerbals something other than Foo Kerman

This has the possibility to create bizarre game modes that may or may not go horribly wrong.

Structure

The grammar appears to be at least context-free in that braces must be balanced. An SFS file can be represented as a tree with two specific kinds of nodes: interior nodes (herein nodes) and properties. Nodes contain other nodes or parameters. Properties are of the form "key=value".

The GAME Node

This appears to be the root node in which all other nodes are contained.
