This game is (semi-) notorious for having a multiplayer achievement that is impossible to get. Even if you do the mission thing perfectly, you just don't get the medal. Wiki says: So I'm wondering if this is true? I was speaking with my brother about this a couple nights ago, and he reminded me that you could send your cart in and get it replaced/patched/whatever with a working cart/ROM. Anyone have any experience with this? First, I'd like to know if the grey carts do actually work perfectly, and second I'd like to know if the carts sent out to whoever (I assume direct to Akklaim) were different in any way - how did they come back? Same cart, new chip? Did they put a sticker on it somewhere to note that it was patched? Did they give you a solid-gold case as an apology?
