Hi, this video shows that it is possible to get all the previous generations of Nintendo Controllers working on the Nintendo Switch. They all require adapters/converters but they all work. I start with the NES and go up the timeline to modern day. In the video I show the controllers working and also the adapters needed to make them work.
Obviously the Joy-Cons or Switch Pro Controller works the best but I just wanted to get all the older controllers working to see if it could be done.
Many thanks Vince
