With this feature, the use can load specific savestates directly from the command line, via the "-x SLOT" option . It is also the foundation for the "Load" button in the Launcher. | |||

They way this works is quite simple: Each savestate has a unique slot number (as explained in the previous section on listing savestates). This number is passed to the engine during instantiation time in the "save_slot" ConfigMan setting. So, all you have to do is to check during startup of your engine whether that config variable is present, and if it is, use its value to decide which savestate to load. In addition, you should specify the kSupportsLoadingDuringStartup MetaEngine feature flag. | |||
