In late 2008, Nintendo (and 53 other companies) took legal action against the makers of the R4 cart, a device which allows, amongst other things, the pirating of games on a DS.

In the wake of last week’s injunction, Yahoo! Auctions Japan has issued a notice e19 that putting R4 devices up for sell on its site is now prohibited.
Even after the Tokyo District Court’s injunction, stores in otaku shopping paradise Akihabara continue to opening advertise the R4, and the device seems widely available. Sure, there betdog might be a lag for retail to catch up with the recent decision to prohibit selling the devices, but don’t expect the R4 business in Japan to dry up any time soon.
