considering bidding on this, is it legit?

I'm very new to the GBA scene. I'm pretty certain this is real from what I've read to check these things, but just wanna check with others who know this better than I do.

Hello someone is selling a CIB copy of Shantae for the GBC. I'm pretty certain it's a reproduction based on comparing other copies of the game. I also messaged them asking for cart/board pics and they said they didn't want to keep taking it out of the box and said true collectors would come look at it, then updated the post. Like I said, I'm 99% certain it's a reproduction but would love additional validation. Thanks in advance (long time lurker, first time poster) :)

Hi could someone help me verify this copy of emerald?

I think they look good, I appreciate any feedback and help. Thank you!

My older one is having problems being read on GB so just making sure my backups are legit

just picked this up and was wondering if it’s real or not

Hi everyone, I recently picked up this sealed copy of bowsers inside story in the red variant.

I am planning on keeping this sealed as a collectors item, so I would like to know if it’s factory sealed/authentic or not.

I’m pretty sure this is a legit copy since I don’t see anything out of the ordinary, but the last time I opened a new ds game was back in 2012.

The only thing that gives me some doubt is how clean the cartridge is. What do you guys think before I buy I buy it?

Are one of these fake? I just bought them both off of eBay. Feeling like one of them is a little different than the other..

Thank you guys 🙏

I’m confident about these games but would appreciate the second opinion(s). Sorry about the photos I had a hard time getting the light to play nice with the PCB and back of the cartridge. I can upload more photos of the back if needed.

Pretty confident all are real. Not the most experienced at verifying, so it could be just unfamiliarity, but the only thing I’m unsure of is the sapphire label has two stamps. One looks as though is says “EJ” the other says “11D”

Just like the title says! I was curious if this is a legit pokemon emerald, hoping to purchase for my partner as a surprise :)

Hi, does it look legit to you ? The sticker is gone though…

Checking to confirm, looks real to me…

This is from Facebook marketplace. I want to check if it is real?

I believe most should be good but would just like verification.

Unfortunately, these are the only photos provided by the seller, and for some reason, they are quite blurry.

Wondering if this is legit. Thank you in advance for all your help!
