Help with Lime3DS

Hello, sorry to bother you, but I barely discovered that Lime3DS works woth my device, and I have been ENAMOURED with the prospect to play Pokémon X like I did all those years ago, trying to play it when I am not scraping to survive. However, that app doesn't work properly with the Ps4 Dual Shock Controller, like at all. It has been paired successfully, and it has been mapped, but 98% of the buttons except for B and Down are not responding. Could I please get some help? If so, thanks in advance.
