Nintendo issued a sinister-sounding warning with the latest 3DS firmware upgrade, cautioning its customers that the use of unauthorized devices like flash cartridges may cause grievous bodily harm.

"Please note that the Nintendo warranties do not cover any defects to or defects caused by unauthorized devices, software, modifications and/or non-licensed accessories," Nintendo states. "Furthermore such use may lead to injury to yourself or others and may cause performance issues and/or damage to your Nintendo 3DS system and related services."

Piracy via flash carts has long been an issue for Nintendo's portable systems, but this is the first time I've seen the company go so far as to suggest that they can cause personal injury. I suppose that such a thing is possible -- some hooligan could potentially develop a homebrew application that totally destroys your eyes with harmful 3D effects. I've heard of DS homebrew apps bricking hardware before, but dang, man. Dang.
