How To Beat Rng In Mario And Luigi Superstar Saga, How Do I Save The Game Once I Beat Cackletta?

In Mario and Luigi Superstar Saga, how do I save the game once I beat Cackletta? - how to beat rng

** SPOILERS **

It is very frustrating. I suggested Cackletta, then Prince Peasly appears and says that he had hidden explosives. They make me out of the castle in search of a checkbox to save the route, and can not find one. After all the credits of the game, restart the game and I'm back, where a registration number before fighting Bowlet disadvantages.

Is this normal? There is no way to beat the game and show that you quit the game? I really hope not. Please help.
