My kids’ Switch plays old NES/SNES/Game Boy games and they still look great on a tiny screen. You can hook the Switch up to the TV but haven’t tried that with the old games. I’ve only a small TV though.Finally got to the point of list of putting emulators on the cinema box and messing about on SNES for an hour.
It's a bit of craic but also I don't think 16bit graphics were intended for a 96 inch screen.
Main pleasure is Kodi on the pii just natively syncs with the projector remote
