The RetroPort is a region-free adapter cartridge made by RetroBit that can play NES games on an SNES. It does this by using a SoC that is built into the adapter. So they technically aren't running on the SNES if more so on the SoC using inputs from a SNES controller. Unlike something like the Super Game Boy, which does run software separately, but "adapts" to it with the video and audio natively going through the console. It's technically "region-free" but it still plays PAL games at a faster speed than normal.
