Alot of us know that bootlegged cartridges exist. My Shadow Dragon cart seems to be the most legit but still bootlegged cart I have ever seen. It looks exactly like a normal cartridge. Almost. For some reason DS and 3DS carts have a tiny indent on the top. Every bootleg I've seen has either had the indent or something else that throws it off. My Shadow Dragon Cart has no indent. It also cannot run on my Nintendo 2DS. Knowing that it cannot run on my 2DS is the fact that the Anti-Piracy is recognizing that its a fake. Oddly though it for some reason worked on my New3ds that i had for some time when it felt like it. After cleaning it several times it would be a 50/50 chance it would work. Interesting eh?
