Back when SNES was still current and flash memory chips were still relatively small and expensive, there were "copiers", which a few SNES enthusiasts still collect just like other vintage peripherals. These are larger devices that contain a floppy drive, DRAM, save RAM, and the necessary logic to provide the most common cartridge mappings. You would dump a cartridge to floppies and then load it into the DRAM to play it. Well-known models include the Game Doctor SF7 and Super Wild Card DX2.
