    FileStream fs;

	if(fs.open(savegame.c_str(), "rb") == false) {
		throw std::runtime_error("Cannot open savegame. Make sure you have read access to this savegame!");
	}

	} catch (std::exception& e) {
	    throw std::runtime_error("Cannot load this savegame,\n because it seems to be truncated!");
	}

    if(magicNum != SAVEMAGIC) {
        throw std::runtime_error("Cannot load this savegame,\n because it has a wrong magic number!");
    }

    if(savegameVersion < SAVEGAMEVERSION) {
        throw std::runtime_error("Cannot load this savegame,\n because it was created with an older version:\n" + duneVersion);
    }
