A rendering of the e-Reader being used with an original Game Boy Advance
The e-Reader (Japanese: カードｅリーダー Card e Reader) is a peripheral for the Game Boy Advance that is used to scan special cards in order to unlock new features in existing games, add new features to games that have e-Reader functionality, or to play minigames on the e-Reader itself.
Developed jointly by HAL Laboratory and Olympus, the original Japanese Card e Reader lacked the Game Link Cable functionality when it was released in December 2001. A re-release, the Card e Reader+, added a Game Link Cable port, allowing it to connect to a second Game Boy Advance or a Nintendo GameCube using the same Game Link Cables that the Game Boy Advance system alone would use. This version of the e-Reader was the one that was later released in the West as the e-Reader in September 2002.
Though it was popular in Japan, with e-Cards released until the end of the Game Boy Advance's lifespan, the e-Reader proved to be unpopular in North America, leading to its discontinuation in 2004. e-Reader functionality, included in the Japanese versions of Pokémon FireRed, LeafGreen, and Emerald, was removed from the English and other translations, as the compatible cards were never planned to be released. Due to this early discontinuation, the e-Reader was only released in North America and Australia, though e-Cards were released in Europe as well.
- "Dot Code Technology" (Optical scanning technology)
- 8 Megabit flash memory
- 64 Megabyte mask ROM
- The long strip on each e-Card holds 2.2 kilobytes of data.
- The short strip holds 1.4 kilobytes of data.
- Passthrough game link port
- The minigame Machop At Work was included with the purchase of an e-Reader.
- According to Nintendo Power v.169, it would take roughly 62,500 e-Reader cards to equal the data on one GameCube disc.
- However, this is a gross understatement when checked mathematically. Assuming the figure listed in the tech specs of this article (2.2KB per strip) and the standard two-strips-per-card format, it would take approximately 350,320 e-Reader cards.
