How To Remap Buttons

You first need to create a rehid.json file with the remappings you want. For eg:-

{
    "keys":[
        {"get":"R", "press":"ZR"},
        {"get":"L", "press":"ZL"}
    ]
}

With the above, everytime you press ZR key, R key would be triggered,

and everytime you press ZL key, L key would be triggered.

It is also possible to do custom key combos, i.e.,

{
    "keys":[
        {"get":"R", "press":"X+Y"},
        {"get":"L+R", "press":"SELECT"}
    ]
}

Now everytime you press X+Y, R key would be triggered and on pressing SELECT button, both L and R would be triggered.

Possible Keys are:- A, B, X, Y, SELECT, START, ZL, ZR, L, R, LEFT, RIGHT, UP, DOWN, CRIGHT(CPAD), CLEFT(CPAD), CUP(CPAD), CDOWN(CPAD)

Copy your rehid.json file to the rehid folder.

Per Title Button Remapping

It is possible to have different button remapings for different titles:-

Inside the rehid folder, create a folder with the titleid as the folder name.

You can use this to find the titleid for your game.

Copy the rehid.json file inside this folder.

Compilation

Get devkitpro, ctrulib and makerom and then make -j to compile.
