Here's the game boxes I have. These are all empty. Some of them are boxes for which I do not have the games -- they came mismatched when I got them. Many of the games have paperwork, stickers, and the mini marquee card.
Spent a few minutes to get the dang batteries out of some Pokemon toys. Past me was smart on the Pokemon Pikachu and the Psyduck. But as for the others, I think those are the original batteries from the 90s!
