I've been checking the internet every month or so waiting for a card to be released that lets me play 3DS games on my 3DS XL, on Firmware Ver. 7.1.0-16E. I'm aware there's at least one kind of card that will play 3DS roms but only on a lower firmware version. I've spotted a few cards that claim to work with 3DS roms on any firmware version, but do they work? Thanks.
