The popular R4 device is a flash cart and MicroSD adapter that allows user to install the custom Moonshell software on their DS and then load ROMS onto the MicroSD card and play them back on the handheld. The R4 bypasses all Nintendo firmwares and loads the Moonshell allowing the game playback as well as music, movies and even classic system emulators.
Although the R4 can run all sorts of homebrew, most use it exclusively to play pirated games, and Nintendo had noticed.
Today the Tokyo District Court has granted an injunction banning sales of the device is Japan.
Most outlets, including online retailers, have already stopped selling the R4, citing pressure from the lawsuit, but the ruling now makes sales of the device illegal in the region.
The 55 companies added that they will now try to halt sales of similar devices, such as the M3.
