Asahi.com quotes the platform holder as stating that trillions of Yen” is lost to pirates each year”, with the controversial R4 device named as the chief offender.
Nintendo's numbers apparently come from a study in 2009 that tracked websites offering pirated games. Throughout the study Nintendo counted around 238m illegal downloads.
The largest areas of activity were centred in Italy, Spain and France.
