It’s theoretically possible they may have done on other devices too. It’s believed the Switch system software is derived from the DS system software. I’ve not seen any breakdowns on what kernels are running in the DS nor on the Wii family of devices either. But there still orders of magnitude more powerful than the N64 too. I don’t think there’s much to be gained in speculation about proprietary operating systems running on newer hardware though.
