Rumble? Dolphin core

If I configure motor L or R within Dolphin, and copy the contents of the Dolphin Emulator folder to RetroArch/saves/User, I can feel rumble during certain parts of games, for example, when the player needs to answer a call through the Game Boy Horror in Luigi’s Mansion, but the rumble is very weak, and almost non-existent during other parts of the game when it should rumble.

I’m not sure if matters, but I’m using an Xbox One controller via Bluetooth, and rumble works as it should in other cores, such as ParaLLEI.
