I analyzed the problem further and saw that;
After changing some RAM memory settings, I want to get through the first fight of the game without crashing, but this only happens when I try to finish the fight as quickly as possible, which leads me to believe that:
- it couldn't be the animations, skills or fighting effects that made the game crash.
- possibly it's something related to the text box because when I don't speed up the fight and try to read the texts, the game eventually crashes
