I bought a GC adapter for the Wii U so me and my friend could use our controllers in Sm4sh but the issue with the one I got is that it rerouted Z to R and made the actual Z button useless, any known fixes I could try to get it working again [Has a PC and Wii U mode btw] (And no I can't ship it back because I bought it in July and just now decided to ask about this).
