I want to finally give one of our Wii U Pro controllers something to do, and use it on Retroarch with this PC I just put together a couple weeks ago. PC's mobo has built-in wifi and bluetooth (ASRock z270 Killer sli/ac), so I should be able to accomplish this for *free* using WiiNUPro. But I dug around for tutorials on YT and found that there was no consistency in the 'how-to.' On the other hand, the Mayflash adapter is $17 or something. Experiences? Advice?
