Nintendo isn’t messing around with the 3DS.
Nintendo wants the 3DS to be as solid of a system as possible, so they’ve gone the extra mile in its development to try and make it “unhackable”. Although that’s something extremely difficult to do, they have at the very least given a warning to all owners by including this message in the manual:
“This product contains technical protection measures. Use of an unauthorized device or any unauthorized technical modification to your Nintendo 3DS system, will render this game and/or your system unplayable.”
I never mess around with my systems as is and recommend you not to either…especially with the 3DS.
