Struct SystemInfo

pub struct SystemInfo {
    pub library_name: CString,
    pub library_version: CString,
    pub valid_extensions: CString,
    pub need_fullpath: bool,
    pub block_extract: bool,
}

Static information about the Core implementation.

Fields

library_name: CString

Descriptive name of library. Should not contain any version numbers, etc.

library_version: CString

Descriptive version of the core.

valid_extensions: CString

A string listing probably content extensions the core will be able to load, separated with pipe. I.e. “bin|rom|iso”. Typically used for a GUI to filter out extensions.

need_fullpath: bool

libretro cores that need to have direct access to their content files, including cores which use the path of the content files to determine the paths of other files, should set need_fullpath to true.

Cores should strive for setting need_fullpath to false, as it allows the frontend to perform patching, etc.

If need_fullpath is true and Core::on_load_game is called:

• retro_game_info::path is guaranteed to have a valid path
• retro_game_info::data and retro_game_info::size are invalid

If need_fullpath is false and Core::on_load_game is called:

• retro_game_info::path may be NULL
• retro_game_info::data and retro_game_info::size are guaranteed to be valid

See also:

• environment::get_system_directory
• environment::get_save_directory

block_extract: bool

If true, the frontend is not allowed to extract any archives before loading the real content. Necessary for certain libretro implementations that load games from zipped archives.
