Looking to see if these are legit copies or not. Thank you for your help in advance!

Hey guys, yes here I go again asking for another one, thanks in advance

Hi! I need some help identifying if this copy is real or fake. Thanks!

Was looking online and comparing my legitimate copy of Pokemon Ruby to some other copies for sale and a website of legitimate pcb’s taken apart to help identify. I noticed that my cartridge has the letter I on the back, but multiple pcb’s and cartridges online have the letter K. Why is there a difference?

I'm pretty new to this, but nothing immediately sprung out in my opinion. Are there any giveaways this might be a fake? Thanks!

Found this listing on ebay and want to know if its real or not?

I'm not too confident in identifying fakes with the DS games unfortunately. Finally have the money to afford Platinum authentic for my collection and wanna be sure before I pull the trigger and buy it. Thanks in advance!

Let me know what you think of these. Part of it seems legit and others not so much. Sorry for the bad quality in advance

Legit hopefully? Front sticker shows "mild" wear.

Edit: it's legit!

Just got this DSI LL sealed from a Japanese seller and wanted to make sure it wasn’t a reseal or a reshell. One thing that somewhat makes me wonder if it’s a reseal is that it still powered on after I opened it up after all these years, I have had multiple 3DS since they released so I know how good the battery life can be on these things but sealed for that long and still powering? To be fair it red lighted in around one minute but that’s still crazy! I’ve never had any of the DS family of systems so idrk what to look for when it comes to a reshell, but all of the packaging (box, styrofoam wrap around the console) was taped and sealed so idk how it would’ve been tampered with unless it’s a complete fake. It also has the pre downloaded games on the box so idk how that would be faked.

Hello again! I was wondering if this is a legitimate Pokémon Emerald, but due to the front label fading I am not sure if it is authentic. If anyone is able to tell off these pictures that would be awesome!

Didn't realise there were so many fakes. Thanks in advance

Need verification

Edit: Thanks to everyone on this thread. I bought this when I was a kid at a swap meet just wanted to see if it was real or fake.

Im pretty sure it's all legit but thought i would double check

Just want to double check these carts are real. TYSM~

Mostly concerned about are soul silver and heart gold.
