Hey. So I found a copy of Metroid Fusion at a pawn shop the other day at a really good price. In purchasing, I forgot to ask if I could test out the game in a system at their store. I figured it would be alright, since the front and the pin connectors seemed legit. When I finally got home and took a closer look (open up with triwing), I noticed first that it saves only with flash memory (I read that some have batteries) and that the second to last pin on the right side was slightly short than the rest (it is difficult to notice at first). I haven't got around to testing it, due to cleaning off the sticker reside on the backside of the cartridge. I think that it is authentic, but that pin....... Would that affect whether I could play it?
