Super Mario Advance 4: Super Mario Bros. 3 e-Reader cards

Super Mario Advance 4: Super Mario Bros. 3 features e-Reader compatibility, in that it can link up to a second GameBoy Advance with an e-Reader. Upon scanning in one of three types of cards, something will then be triggered in the game.


 * Power-Up Cards: When one of these is scanned, it will upload an item (or a set of items) into either Mario or Luigi's inventory. There is no limit as to how many times an item card can be used. A variant type of Power-Up Cards are Switch Cards, which will trigger something in the game upon being scanned.
 * Demo Cards: Plays a movie of either Mario speed-running through a level, collecting enough coins in a certain level to trigger a Blue Toad House, or racking up numerous 1-Ups via a special trick.
 * Level Cards: Uploads a brand new level into the game, which can be played in World-e.

Cards
The majority of the cards were released in two series (sets) of cards. However, a few cards were included with brand new copies of the game. While most copies only came with two cards, copies purchased at Wal-Mart early on came with an additional five cards.

Roughly only one third of the cards that were released in Japan were released elsewhere. Therefore, there are over twenty levels that remain unavailable to non-Japanese players. Other missing cards include various Switches and Boomerangs.

Note: Due to the discontinuation of the e-Reader, newer copies of the game do not come with cards, although the game itself is still compatible with the e-Reader.
