Hey I have that. I find it too bloody hard lol. I made a noob mistake today. I saw GBA Ninja Cop in CeX today and paid 25 quid. I did look it over, it had the Nintendo white print on the PCB, proper cut off on the back and numbers pressed into the label, but I overlooked the Gameb Advance text embossed on the front, it's too thin, plus the label is slightly incorrect. Was worth the chance tho. I'll be going back tomorrow for a refund.
