Seems like Japan have been trying to cut out sales of flash cards again. From what i can gather from the news posted on yahoo japan is that a new bill was passed to completely ban the import and export of flash cards. Basically it sounds like they they will try to stop them coming into japan at the border, and anyone caught importing/exporting these devices can face a fine and up to 10yrs in prison. Japan had previously tried to put a ban on the R4 but it never seemed to stop much and is probably why this new bill was passed.
