3DS consoles may be capable of monitoring when flash carts are used to play pirated games, with the further possibility of Nintendo disabling systems being used in this way via firmware updates.
That's according to reports that sprung up following a warning from Japanese retailer Enterking. Here's rough translation of what it said on its website, via Go Nintendo.
"Dear customers who resell Nintendo 3DS... If you use equipment which is illegal or unapproved by Nintendo or if you do customisation which is unapproved by Nintendo, there is a possibility that Nintendo 3DS becomes non-bootable by system update.
"Because of terms of agreement above, Enterking refuses to buy 3DS system with record of illegal or unapproved equipment."
Responding to the retailer's warning, Nintendo gave Eurogamer the following statement.
"We do not discuss product security details (for obvious reasons), nor can we discuss the details of countermeasures available in the Nintendo 3DS system.
"Nintendo 3DS has the most up-to-date technology. The security has been designed to protect both the creative works in the software and to protect the Nintendo 3DS hardware system itself."
THQ's executive VP of global publishing, Ian Curran, told us last year he was confident that all-new anti-piracy tech in 3DS will be foolproof to cracks from illegal downloaders.
