Just made a custom wii remote with 2 broken ones.

I had 2 broken wii remotes (1 with undetected problem and the other one by dead batteries) and combined both to make a custom wii remote that uses half the case of the pink and half the case of the black and white (both were fake if you ask for it) and replaced the metal part corroed by the dead batteries with the one of the black remote, and it works perfectly.

Result:
