Of course, you still have to include a copy of the Nintendo logo to get past the BIOS check, even if it's not displayed, which I think is supposed to be the trademark infringement.

Yeah i think this is the bit that a brave publisher could have argued in court, I think for it to be a trademark violation it would have to be visible somewhere beyond the raw content of the ROM. That's why i'd argue it's essentially being used as an API token, and trademark definitely doesn't cover that.
