n 2003, the fourth in the "Super Mario Advance" series, was released for the Game Boy Advance. It is much the same graphics and sound to the "Super Mario All-Stars" form, and made use of the e-Reader. A few e-cards came with new copies of the game, while two sets (called "series") of cards, were released and sold with the game. By scanning special cards into the e-Reader, players were able to send items, videos, and most importantly, new levels into the game. One important item was the Cape Feather from "Super Mario World", which let Mario change into Cape Mario. There were also two Switch cards that the player could turn on (and turn off) the effects of by scanning them; the Orange Switch and the Blue Green Switch. Scanning these switches set off small uses in the game. The e-Reader item is still available in the European form, but has been turned off and cannot be used anymore.
