So, I was looking to trade in some stuff to Amazon to get that 50% off coupon. I started looking at GBA trade in stuff, and found that Pokemon Ruby has a value of $13! So, I want to trade in my copy, but I'm a bit confused about what it needs. Now, I know most games require the case, manual, art, and game. But what about GBA games? Can I trade in just the cartridge, or does it need the original box, etc? Who keeps those anyway? I looked around on Amazon to try and find an answer, but I couldn't find anything. Anyone know?
