The sure fire way to identify fake GBA games from real ones?

Question

I know I have asked a questions like this time and time again but this one is slighty different.
I would like to assemble the sure fire way to identify fake GBA games from real ones.
In other words a guide. I have searched for guides but a lot of them are contradicting each other.
So I would like to find out the right way to do it.

They can be forged, but a real one is "official" therefore not fake. :P

Okay, I don't want to try explain it so I'm just linking to the page here.

I don't think any of it is that necessary, until you get to:

And it will go on about dismantling or insecting or whatever-you-call-iting the cartridge to see the PC Board. I know nothing about technology, so just read before my head explodes. xD

Hope I helped. :)
