Pokemon fake games?

Hi, I bought GBC/GBA Pokémon games from ebay and I would like identify, if they are truly legit. They are reflecting, all seems good, but only imprinted numbers are inside(on the place of) the CE marking (I bought europe version) in case of GBA games or inside of quality seal in case of GBC games. All imprinted symbols are in the right side.

Do you think, it's OK to have imprinted symbols inside the CE or quality seal?

@fugar: Best way to tell is to look inside with a flashlight and above the copper contacts will be a series of numbers. If you see the numbers, its the real deal. Can use this site, they have some good stuff. Just have to check everything and try you best.

@mesome713:Thank's. I studied it befor buy a lot. Problem is, I'm about to pay for it and it's still on seller side. I can't look inside.

From outside everything looks fine. I'm just confused about the position of imprinted number. I think the important is, that it's on right side and doesn't matter, if it's imprinted in CE, quality seal or above. But I'm not sure.

@fugar: Dont they offer refunds? I usually buy from people who offer them. Will help some encase. Good thing though is that its not common to get fakes. Also check their seller rating and reviews if they have it.

@mesome713: Nope, it's auction. But if games will be fakes, I will try refunds.

But still, if anyone will know the answer about imprint placement, please write.

@fugar: Check out here, they talk about them some. Also the second post looks awesome and deals with GBA games. Its bout all the info i can get for now since the game is on. But hopefully it helps some or someone else can help answer here.
