Nope. As other have said but I'll iron out for 100% confirmation - these are still emulators of the original system, from a single chip, the exact same one as the built-in systems. The sole difference is the location they're reading data from - instead of the flash chip that stores the in-built ROMs, it's the real cartridge via the datalines to the chip. In terms of what it's doing once the game starts running, it's exactly the same as if it was running on any other Atgame system. Shitty sound and everything.
