Good eye! I didn't even catch that one! I also think the Road Rash GBA Game is a fake due to the chinese letters, but the GBA fakes are probably little more than just copies of the legit cartridges.
That makes at least 3 pirates in this lot. Can we at least confirm the Pokemon is legit?
Anyhoo, since nobody else has jumped on, I'm planning to go for it. I have every type of american GB besides Pocket and SP so the Tony Hawk pirate is bound to run on at least one of them. As long as it doesn't get too crazy pricey, I'll pursue it for the community.
