/* File paths:
* File paths passed as parameters when using this API shall be well formed UNIX-style,
* using "/" (unquoted forward slash) as directory separator regardless of the platform's native separator.
* Paths shall also include at least one forward slash ("game.bin" is an invalid path, use "./game.bin" instead).
* Other than the directory separator, cores shall not make assumptions about path format:
* "C:/path/game.bin", "http://example.com/game.bin", "#game/game.bin", "./game.bin" (without quotes) are all valid paths.
* Cores may replace the basename or remove path components from the end, and/or add new components;
* however, cores shall not append "./", "../" or multiple consecutive forward slashes ("//") to paths they request to front end.
* The frontend is encouraged to make such paths work as well as it can, but is allowed to give up if the core alters paths too much.
* Frontends are encouraged, but not required, to support native file system paths (modulo replacing the directory separator, if applicable).
* Cores are allowed to try using them, but must remain functional if the front rejects such requests.
* Cores are encouraged to use the libretro-common filestream functions for file I/O,
* as they seamlessly integrate with VFS, deal with directory separator replacement as appropriate
* and provide platform-specific fallbacks in cases where front ends do not support VFS. */
