Japan blocks sale of R4 carts
A Japanese court has ruled that the sale of DS's R4 cart is illegal.
From Kotaku:
The Tokyo District Court has found against the Chinese makers of the R4 - officially known as the "R4 Revolution for DS" - and granted an injunction against sales of the device, prompting Nintendo, Square Enix & Capcom to issue statements proclaiming that they're a "violation under Japan's laws".
Most outlets have already halted sales of the R4 following pressure from the lawsuit (and the publishers, such as Nintendo & Capcom, backing it), but this ruling now makes it official: you can't legally sell the thing in Japan.
More through there.
