The long, unskippable speech right before the third gym battle makes rematches absolutely painful, especially on Hard. Something has to be done to make this able to be skipped.
I mean, you can save just before the battle where he says, nothing personal and if you know about the speed up button, just use it and keep mashing a until the battle starts. If it IS really painful, make an exeption and change that one battle to medium or easy. I personally needed 2 tries to beat him in EASY mode so yeah.
I tried to save during the dialogue but it seemed to not allow me to do this. I did eventually beat East on Hard but the speech still needs some sort of skip. Same goes with basically every time there’s a speech before a hard battle.
If you want to skip it, just change that one battle to traditional mode and it will skip it.
