POKEMON fake help

[Megatron]

Hey guys,

Long story short, I acquired a box full of random games at a pretty good price.  Most i am keeping, but some I either don't need or don't want.

Which leads me to these...







Pokemon Ruby, Sapphire, Leaf Green and Fire Red.

I have no idea if these are legits or well made fakes.
Ruby has no label, but that isn't necessarily a tell.  

Fire Red is questionable due to the board looking different, however it loads in Retron 5, plays fine, saves, and GBA action replay even acknowledges it for cheats.  Can this be true of fakes?

Any info anyone may have on the legitimacy of these games would be greatly appreciated.

Thanks!

they look alright, is there an alphanumeric stamp over the nintendo seal of quality, imprinted into the cart label?
i see that ruby is missing the label... i think.
but i think the innards look like mine... except i put a new battery in it, a 2016 instead of the OEM 1616.

they all look good... 2 things to look for

large "E"
the embossed number above the nintendo seal of quality

The ruby is definitely in a knockoff replacement shell, but the board looks legit. Like everyone else said, all the boards look good.
