1Ninten110Fri 17th Apr 2020 I was studying the details of my DS game collection, and noticed this strange oddity which I've never seen before on any of my other DS game cartridges. This is on my "Nintendogs: Dachshund and Friends" copies. I own two of this exact same copy, both bought used from GameStop. On the contacts of the game chip, where a line of numbers would normally be, one specific copy says "Nintendo", followed by three numbers, whereas one just has the regular line of numbers. I've never seen another cartridge saying "Nintendo" on the contacts. Both of these copies are exactly alike; both official, both US versions, etc. So... what's up with it?? I'm new to the forums, so if someone could explain to me how to upload images, I'm sure that would help a lot more than my crappy explanation of this phenomenon.
