I recently purchased the Mayflash Classic Controller USB adapter:
https://www.amazon.com/Mayflash-Wii-Classic-Controller-Adapter/dp/B07BN49ZFR
It works fine aside from the fact that there are random inputs from time to time (You'll notice a number of people with the same problem in the Amazon reviews). The most noticeable ones are when the L and R bumpers are randomly activated. I've tried both a Classic Controller Pro and the Tatsunoko vs. Capcom fightstick and issues occur on both. Here is an old thread I was looking into yesterday discussing the issue:

The issue is not exclusive to Dolphin either. It's happening for me in Flycast as well. Any potential fixes and help are much appreciated!
