“Police in Japan have arrested a 36-year-old man on suspicion of selling illegally modified Pokémon save data to customers online”
He sold custom Pokémon for up to 13,000 yen a pop, about $84, and six-packs for roughly $30. Japan’s 2019 Unfair Competition Prevention Act makes that worth up to five years in prison and a 5 million yen fine. A “police cyber patrol” caught him editing move sets. Japan has decided that tweaking a save file on hardware you own is a crime worth hunting.
