The evidence seems to be mounting that classic Nintendo 64 games are on their way to the Switch, and in fact, it seems The Big N may be planning to release a replica N64 controller for the system. Nintendo recently submitted a new Switch controller to the US Federal Communications Commission (thanks to Video Games Chronicle for the find) which is a requirement for any device that sends a wireless signal.

The model name for the new device is HAC-043, which indicates it’s for the Switch – HAC-042 was the code for the wireless SNES controller Nintendo released back in 2019. The filing holds back on most details as Nintendo has requested six months of confidentiality from the FCC, which would seem to indicate the device is being released within the next half year.
