What I mean is that the SNES cartridge for Super Mario RPG had a SA1 enhancement chip which is a processor that's faster than the one shipped with the original console, the Ricoh 5A22.
So unlike most games today which are mostly a ROM device, SNES games were actual computers on a cartridge.
Oh I see.. I thought you were saying that the switch cartridge had an embedded controller that was faster than the SNES processor (and probably the SA1 chip too)
But I think they were saying the chip in the cartridge this time is faster than the chip in the cartridge last time (which was still faster than the SNES's processor)
