The onset of wireless gaming controllers was a big moment for me. For years I lost good gaming sessions to people, dogs, or other animals running by the TV and pulling the system down by the controller cord that snaked its way across the living room.
The NES was long before the time of wireless controllers, but through the magic of hacking we can change that. This Drop-in TX Board and receiver lets you turn your generic NES controllers into wireless variations.
Since the controllers aren’t very big, the seller recommends a 200mAh 3MM thick LiPo from AlliExpress to ensure everything fits. This should get you about 13 hours of game time on a single charge.
Installation instructions will help you modify the controller and solder the leads from the LiPo battery to the board. Once that’s finished, you’re ready to bring the NES into the wireless world.
