Got yourself a Nintendo 3DS? Great! But if you're one of those who uses a flashcart to play games or planning to - I have bad news. Enterking, a Japanese retailer, has issued a warning that using equipment or customization that is illegal or not approved by Nintendo, the 3DS will automatically brick by system update. How true is it is still unsure and how Nintendo will push the update or how Enterking will be able to tell (maybe they are able to see the logs in the 3DS?). But to be better safe than sorry, stay away from Flashcarts.
