So, throwing away that copy of Pearl seems to be the obvious answer, now that I got a refund for it. However, with Diamond, I'm not sure whether to give it away or throw it away, but I'm leaning more towards the latter. If anyone else plays it, they'll be in for a disappointment if the data ever deletes itself. When I bought my fake copy of Pokemon Sapphire, it took four months for the data to delete itself, after which I could never save again until I got it replaced.
So anyway, I'm planning on buying used copies of Diamond and Pearl from GameStop when it gets closer to Christmas. That way, when I get a Nintendo DS-i, I'll probably have some Pokemon to trade from those two games onto my own copies of Pearl and Platinum, before I delete the data and wrap them up as Christmas gifts.
So, considering that DS games have different storage methods, that Pearl deleted itself, and that it took four months for Sapphire to delete its own data, does anyone here think I should give it away or just discard it completely?
