A question about a bought Wonderswan Color

[noname]

Okay, so I bought a CIB WonderSwan Color just a few days back, and it may have a Final Fantasy ad, instead of a WonderGate ad, which I saw in some of the other auctions. Now, I'm asking these. Did the Final Fantasy ad replace the WonderGate ad while the WSC was being sold? Or maybe, was it packaged with the WonderGate ad? Or maybe, was it an ad which was placed by the seller to replace a missing WonderGate ad? And, is such an ad rare to be packaged with the WonderSwan?

For more clarifications, look at the seller's* other WonderSwan Color, and another seller's WonderSwan Color, with the WonderGate ad. If you see closely on the images of the former, there is something which resembles Final Fantasy.
