The Japanese government has cracked down further on flash (R4) cartridges for Nintendo handhelds.
Prior to the import ban, it was already illegal to sell the devices at local retail, meaning Japanese residents keen to use one are left with little legal recourse to acquire one.
The flash-powered devices, commonly referred to as the near-generic R4 cartridges, allow users to load custom software on Nintendo portables including the DS and 3DS. While homebrew users often have harmless intentions, the cartridges are more widely used to pirate software.
