It's worth the small subscription fee, because all you do is go into the Nintendo store on the switch, go to the SNES/NES parts, go into any game and do the free download which should give the emulator back on your home screen. Then you open that and all the games are there for it, the ones they have on it anyway. 🙂
Ah yes, good to get games you have been looking for and wanting for a while.
