There was no special chip on the cartridge either, not sure where you heard that from.

Hmm, I may be conflating or misremembering some details, possibly involving the Earthbound Zero prototype cartridges that were floating around for a while. It's been a long time, but I do distinctly remember that very early in SNES emulation on PC, that there was a bit of a struggle getting Earthbound (Mother 3) to pass the piracy checks, though every emulator for the last ~20 years handles it just fine now.

It may have been a different Nintendo console that did a voltage check. But I'm pretty sure I didn't just make that up out of nowhere. Now it's gonna drive me crazy figuring out what I'm trying to remember. :(

    TCRF has the exact implementation documented. One thing that's commonly missed in the urban legends that get passed around about the game is that the two hardware checks prevent the game from running at all. It's only the ROM checksums to see if those routines were tampered with that will then trigger hard mode. The point of that is to trick anyone trying to crack the ROM who might think they succeeded if they got their modified ROM to boot on a cartridge copier.

    But this does mean that unless you modify the ROM, no emulator will ever trigger hard mode, an unmodified ROM will either run or it won't.
