Hey. I have my GC controller plugged into my computer via Mayflash adapter. Before you ask, I did already read Dage4's guide on a reply to https://www.speedrun.com/sadx/thread/utp1a/1#06b6z <- this thread. I set it up to work with Dolphin before doing this fix and for some reason it's not mapping my buttons that I press. For example, whenever I try to map a button to a control, it simply does not register, no matter what button I press. does the setup to work with Dolphin conflict with this? Please help!

Hi dude, I had the same issue, I solved simply removing the drivers of the Mayflash adapter.

Really? That's an odd fix. After getting a new X-Box One controller for Christmas I've found that even when using X-Input fix v2 that controller didn't work either. Maybe I missed a step?
