Does anyone know if the ABXY buttons from the smaller New 3DS fit in the New 3DS XL? I wanna switch these out for the more colourful ones that are on the smaller version

Sort of. Some of the buttons like A X Y can fit the notch (Barely) but the B button has a bit of free movement. But it’s usable.

no, but if you cut the notches in the buttons it will fit (it’s the same diameter)
