Some new anti-piracy warnings have propped up on the back of 3DS game packs.
As noted by CVG, the message can be found on the back of 3DS software packaging and it says:
“This product contains technical protection measures. Any unauthorised technical modification to your Nintendo 3DS system or the use of an unauthorised device (flash cards) with your system may render this game and/or your system unplayable.”
This means your 3DS can be unplayable if you use the device in any unauthorized manner. You have been warned!
