4th Gen Pokemon Pearl fake or not

Hello.
I received this one from the EBay, but I don't know is it true or fake.
I tried to figure it out through Google, but I still doubt.
Please, help me.

Also, the booklet

I'm not really an expert on this sort of thing, but comparing your photos to my own copy of Pearl, it looks identical as far as I can tell, and so I would assume it is likely legit.

Well I know for a fact my USA Pearl cartridge is legit. My DS packaging for it is loooong gone.

I went through your front & back cartridge pics w/ a fine tooth comb (cart itself, sticker itself, nintendo seal, codings, & patent# stamping w/ size/font type) & compared to mine. Everything checks out exactly as it should. The metal/green strips where you insert cartridge contains nothing flagging either (though mine is badly worn from years of over use).
I'm 99% positive you have a completely legit Pearl cartridge in your possession.

Thank you, guys
