I just snagged an NES mini this week and of course modded the heck out of it. I picked up TWO 8bitdo retro receivers, so that I could use my existing controllers, such as my Wii U Pro controller and my Switch pro controller. However, updating the firmware on them to give Switch controller support, the receivers will not light up when plugged into the NEW mini. They act as if they're dead. I can sync them back up onto my PC, but I have to revert them back to v1.05 beta to restore normal functionality.
I searched around for answers, but no luck... so here I am! Anyone know what the problem is?
