I'm surprised nobody has made SD cards with mask-programmed ROM or even traditional write-once PROM.

  It's called a Nintendo DS game card. I don't know if the Switch game cards are flash or mask-ROM.

    Mask ROM.

    I don't have a source, but I think I remember reading somewhere that Switch games are some kind of archival flash, designed for 50+ year retention.
