+Notes:
+
+- `MountPhysFSFromMemory()` does not copy `fileData`; the buffer must remain valid until the mount is unmounted with `UnmountPhysFS()` or `ClosePhysFS()` is called.
+- On raylib 6.1+ the `data` parameter of `SaveFileDataToPhysFS()` is `const void*`; on older raylib versions it is `void*` (see `RAYLIB_PHYSFS_SAVE_DATA_CONST` in [`raylib-physfs.h`](raylib-physfs.h)).

 ### Raylib Platform
 
 [`physfs_platform_raylib.c`](physfs_platform_raylib.c) implements the PhysFS platform abstraction layer using raylib's own file API (`LoadFileData`, `SaveFileData`, etc.). This is useful on platforms where raylib provides a custom file I/O layer.
