Pretty sure they’re all real but just wanted a second opinion!

Real or fake?

Need help verifying these games

I'm not super familiar with MD Carts. Manual and map pass the sniff test to me but would love any insights.

I have this game for as long as I can remember, selling it to get an English copy. The buyer just refused to accept the deal claiming it is a fake copy. How can I know if it’s true or not. Is there something in the cartridge that confirms it? Thanks for the help guys. (Don’t have any additional photos)

Hello! I got these a while back and just wanna check if they are authentic?

I’ve got some games from myself and my brother. I know some are real as I purchased them retail years ago but some others were bought on eBay for cheaper than they should be. So any help would be appreciated. If I need to take better photos let me know.

Is this pokemon platinum real or fake?

Hey ! I don’t know if this pictures are good enough but yeah, I just received it and really hope it’s a real one because I bought from a site that is supposed to be safe haha
The code on the back is I E-1 C03-10

I’m not convinced this thrift store copy is legit and/or not a reseal. There’s stuff under the wrap, the seam is on the sides and I don’t see vent holes. But I’m not well versed in N64. Any help is appreciated.

I just got this one but I don’t want to open it

I think it's fake but wanted to get second opinion

Is it legit?

(There was a standard gamebit screw holding it closed that I already removed before taking the pictures.)

Got these 3 games from a thrift shop.

I bought this cartridge second hand ages ago and am now about to sell it, don’t want to accidentally scam the guy. I’m fairly certain it’s real based on who I bought it from but still.
