This happened to me just this week. I finally - FINALLY get a Pokemon game that will allow me to dual slot & move 1 more step toward completing a dex & I find out its fake. It wouldnt allow the option to migrate to come up. For like 2 days I figured I was doing something wrong but then somebody told me that this is what happens with bootlegs SO.... I decided to look at the guy's feedback on eBay & he had well, really there were only about 3 or 4 others complaining of getting fake games but they were all recent and all were from Pokemon games so I figure it has to be more than just a coincidence. It just doesn't make sense because I have *definitely* met all of the requirements to be able to transfer Pokemon from Emerald - if the game cartridge were legit.
I'm so mad. I filed a complaint with eBay and I guess I'll try to get another copy since I expect to be getting my $18 back.
Thing is, I can NOT really strongly tell any visible difference in the cartridge. I tried to compare by looking at sites that provide comparisons in fake vs real catridges & I GUESS they do look kind of different but its not glaringly obvious. But I say all of my reasons described above added together make it like, yeah its gotta be fake.
Aint nobody got time fo that.
