Context: In the past two years, I've been searching for a copy of Diamond, Pearl, or Platinum. I bought a Platinum cartridge from Gamestop two years ago and it was very pricey. When I started playing it, it would always freeze. My saved progress would also get erased by itself. I've always questioned whether it's a fake copy because of the game-play and the blurry sticker. Today, I concluded that it's actually fake. I compared it to my authentic SoulSilver, seeing that the white Nintendo DS bar was larger and a little more bold. This is the first time I got scammed.
Two days ago, I bought a cartridge of Pearl, on ebay, from a seller who has 100% feedback, however the seller sold over 60 copies of it, and it actually comes from China, despite the seller resides in Utah. This was the second time I got scammed for buying a generation 4 game. I received the cartridge yesterday, and turned out to be fake. The Nintendo logo on the back didn't match my Soulsilver's, and the E for the game's age rating wasn't bold enough. I tested it, and it worked fine. But, I don't want to face the same issues I had with Platinum, like save files being corrupt and the game always freezing.
Edit: I gave gamestop one more chance, and they gave me an authentic copy of Pearl. The condition was good. The price wasn't so bad.
