Nintendo 3DS just arrived in Japan, and hackers already got successful in creating a tool by means of which R4 catridges can be played by on the handheld. However this doesn't means that pirated 3DS games can be played on handheld, it implies that gamers can play pirated 3DS software on it. This is consider to be the very first hacked of the handheld as it is mandatory for 3DS software to be bypassed in order for this to work.
Regarding actual 3DS software, developer are claiming that 3DS software will not be that easy to hack or steal as Nintendo DS because, anti-piracy measures have been increased for the 3DS.
