These 18-card decks of code lets you program your GBA or GBA SP with new Pokémon and Pokémon activities, as long as you have an e-Reader. Each deck consists of two 9-card sets, with eight trainer cards and one berry card. There are two Pokémon sets: Hidden Ruins and Iron Defense. As the cards are scanned, the new Pokémon and activities gradually appear. To use the cards, you need a GBA with either Pokémon Ruby or Pokémon Sapphire, plus a Game Link cable (not to mention the e-Reader). Other e-reader decks come for Super Mario Bros. 3.
