Eu fiz um código aqui, tenta ele:
Scene_Boot.prototype.start = function() {
Scene_Base.prototype.start.call(this);
SoundManager.preloadImportantSounds();
if (DataManager.isBattleTest()) {
DataManager.setupBattleTest();
SceneManager.goto(Scene_Battle);
} else if (DataManager.isEventTest()) {
DataManager.setupEventTest();
SceneManager.goto(SceneMap);
} else {
this.checkPlayerLocation();
DataManager.setupNewGame();
// SceneManager.goto(SceneTitle);
// Window_TitleCommand.initCommandPosition();
DataManager.setupNewGame();
SceneManager.goto(Scene_Map);
}
this.updateDocumentTitle();
};
