Meh, 20 bucks minus whatever I bought it for MINUS ebay/paypal fees = not worth it for me. If I'm going to resell anything, I need to make 100+ to give a crap.
Man, you got lucky then. I've heard so many horror stories, not to mention my neighbors who've bought many bootleg Pokemans games in the last 6 months that have all been total shite. Some save, but then the file corrupts, others don't save and all, and some just run out of data once you hit a certain point in the game.
