Read the 16th post in this thread. There is a good FAQ on how to spot bootleg gba games.

That minish cap is definitely a bootleg.
I was bored hanging out at a friend's gamestop waiting for him to leave, so i went through the GBA games and pulled out the bootlegs. 15-20 in all. Some of them were priced as "Generic GBA" because there was no such title in the system.
I'm just curious how they get over here. Is there really that big a market for people to smuggle in bootleg GBA carts and launder them through Gamestops, or is Gamestop buying them outwright from the pirates?
I wouldn't really put it past them...
