Hello, I just wanted to contribute something to continue complementing and referencing.
I bought the KingKong2 PRO Controller from GuliKit, soon I will have a switch and I thought of it as an investment in the future since it works for both switch, PC, android etc.
The thing is that out of curiosity and remembering GaryGaryOderNichts who told me that if it works for switch, the theory is that it works for bloopair, well, yes, the theory is already practical, if it works, the good detail I didn't know what would happen, but the wiiu (maybe I don't know if it's bloopair or it's the wiiu itself) it recognizes it as an android remote, I thought, I don't get it either because I thought that, but I thought it would recognize it as a switch, which it does recognize, by the way, but it doesn't work, until It was my fault that I gave it sync and changed to Android and it works perfectly there.
and that's all, thanks for reading, greetings.
