so beware of this bootlegs.

I got a white stickered minish cap from a kid who got it from Thailand, and the back of the cartridge says "Nintondo". Everything works great exept it freezes during the credits, so I can't get the mirror shield.

BTW there are THOUSANDS OF THESE SELLING ON EBAY, Ebay JUST NOW sees this as a problem (now that someone else has brouhgt it to thier attention (they can't ignore it anymore without reprocussion to themselves also). EVEN AS OF TODAY there are DONZENS that I spotted still selling BUT proving it to ebay is yat another challenge to catch them..

iNTERESTINGLY i'M A SELLER ON ebay and I noticed it too. these cracked sellers are selling ONLY the games which are highest rated, they are ALMOST NEW to sellng (according to thier sales numbesr yet they have incredible ratings from people, selling the SAME GAMES over and over. you wil see about 20 or 30 ebay ads all with the same FONT and graohic layout, all selling ONLY the highest selling DS games and sold for the CHEAPEST around. If you read thier reviews at least ONE person pics out that they're selling fakes before the guy folds and opens his shop under a new name.

ALMOST always shipping from HONG KONG and sold from Australia or some other similar SETUP OF shipping from a diff country that sold in. They usually only sell about ten types of games. But they keep selling them! over and over, the same popular ones!

These ads are easy to spot once you start knowing what to look for. And YES, many people DO buy them and happily use them and often never realize they are playing b ootlegs. Just go into a stor like Game stop and you'll see only about 5 of some classic game and then 100 BRAND NEW POKEMON Ruby (Older game) that were traded in, when they realized they were fake and often they dont even realize that after all. Game stop doesn't care as long as they play…

THINK!

WHY IS IT [the cart] NOW brand new if it is actually so old a game ?

Check for yourself… Even your local trade in store is loaded with them now as trade-ins.

[...] didn't find anything, but found this site describing the difference between a fake and real copy. A counterfeit GBA ring operating out of my car hole! Er, ebay! Cracked Rabbit Gaming.

Seeing as nothing has come up on the boards so far, I don't think this is that widespread a [...]

You gotta give kudos to the guys who came up with the way to make them look so similiar.

If the ebayer is still selling, there's a way to report them to ebay. People have said ebay doesn't really do anything, but you can try anyway. I didn't bother since the person I bought from wasn't the actual bootlegger, and I don't think he's scamming other people.

After reading this I checked out a GBA cartridge I got from the UK, Dragon Ball Advanced Adventure. When I first received the cartridge everything looked fine and played great. However it would not hold a save game. Of course the eBay seller "nationwide_delivery" (item 8283540544) never decided to return my mails about this "Tested" game. But sure enough the Nintendo on the back looks thin and there is no Nintendo stamp on the circuit board. Thanks for making me aware.
