I am wondering if there is a script that will check if you have a certain pokemon in your party that will set a flag. For example I have a pikachu in my party, then it will trigger an event after I talk to someone or something like that.
Actually this is to do with ROM Hacking. Which is why I will direct you here. Hopefully you'll find an answer to your question within that section. In future, just be sure to read the section descriptions before posting in them, so as to avoid posting in the wrong place. Best of luck finding your answer. Closing this.
