Super Mario Advance 4: Super Mario Bros.
© 2003 Nintendo of America
Software comes in all forms, and this is a great example. Originally released on the NES (Nintendo Entertainment System), Super Mario Bros. 3 was at one time the most popular video game in the United States. Now the code has been put onto 18 cards, with printed codes (like bar codes) that can be read by the Nintendo e-Reader. There are two sets of cards, with different levels. As each card is scanned, the new activities gradually appear. To use the cards, you need a GBA, and a Game Link cable (not to mention the e-Reader). Other card decks feature Pokémon. Buy it or borrow it.
