Get to a shop, let the cursor go over "Buy", and push the "confirm" button followed immediately with the "cancel" button. If you were fast enough, the characters should still be displayed even though you aren't shopping anymore. Now, if you select "Buy" again, the game will, most of the time, freeze up; else, your characters should be duplicated. If you access the "Sell" menu, you should still see them, and you can see them react in one semi-random manner depending on which item the cursor is pointing to. For exemple, the game may pretend that a Dried Meat is better equipment for Terra, or even better, for a blank spot.
