@TERRORBOGARD Sorry, you are right, in RPi3 there is only one core.
I tested the game, and randomly managed to hit some specials (but the problem is not the controls: I am very bad at this game...).
Have you tried to access the Retroarch Menu and change / customize the control settings for this game?
Open the game and press Hotkey + B, navigate through this menu and you will find the control settings.
