About a few weeks ago, I bought Pokemon White 2 and when I first started it up, I was shown with this screen. I've tried every method of cartridge cleaning but to no avail, even though the cartridge looked just fine, and I have other DS games that looked worse and play just fine. I've just recently gotten my 3DS modded, but I don't know what to do after that, let alone if you could check what's wrong from over in the game files from the cart to fix this issue, if that's possible.
