NES, SNES, N64 and Mega Drive controllers now work on Valve'
The official NES, SNES, Nintendo 64 and Mega Drive / Genesis controllers, which remain on sale only to Switch Online subscribers, can now be used to play games on Steam.
The patch notes for the July 27 build of the Steam Client simply say: “Added support for Nintendo Online classic controllers.”
However, a Valve spokesperson confirmed to The Verge that this specifically referred to the NES, SNES, N64 and Mega Drive controllers.
