Remap controller buttons Wii console

[Liquid_Snake]

Hi, I recently bought a modified Nintendo Wii to play Metal Gear Solid: The Twin Snakes PAL version.

I also bought an 8bitdo adapter to use the Sony PS4 wireless controller, but I'd like to know how to remap the buttons because the Nintendo controller's buttons are awkward.

I read that you can do this with Ocarina codes. Can you tell me how?

Thanks.
