I bought Pokemon Platinum and I opened it because I wanted to know if it was original. Everything else points that it is authentic even the registering code in the paperwork whowed me in the nintendo club that it is Pokemon Platinum. However I know that the pokemon games uses MX chips inside and this one has other kind of chip. It has the nintendo logo printed on it but the chip is Sandisk not MX.
I have attached 2 detailed photos of the cartridge and its chip. Could someone please explain to me why the chip is different?
