The e-Reader uses a variation of the technology used in QR codes. QR codes, surprisingly date back as far as 1994. Old-time internet layabouts like myself remember the CueCat, a special barcode scanner that was given out for free, under the assumption that they could make money off of them from advertisers using their tech to encode URLs to their sites in their print ads, then users could scan them with their CueCats to jump immediately to their sites. Yes, this was a business model that people once thought could work. Maybe it could have at one point: that’s the major use case for QR codes now.

The e-Reader was rather different. A Gameboy Advance peripheral released in Japan in 2001, and the US in 2002, it could scan tiny dot patterns printed on playing card size pieces of cardboard. Whereas QR codes are intended for small amounts of data like URLs, a single e-Reader card could hold 2,112 bytes of data. The hardware itself had a ROM built-in that contained an NES emulator, so one of the things that could be distributed, on small decks cards, were smaller NES games like the black box series. I had an e-Reader myself back then, and while it’s long since misplaced and probably lost for good, I still have an officially-released pack of cards somewhere with Balloon Fight on it, and also the weird e-Reader variant of Mario Party, which I think I’ve only ever had the chance to play once.

The e-Reader was one of Nintendo’s shorter-lived play experiments, and didn’t last long. But one of the most interesting releases for it was a large sequence of Animal Crossing cards. There were hundreds of these cards, and they were kind of like an early version of the current-day Animal Crossing amiibo cards. It’s amazing there were so many, because the hardware requirements were significant: you needed a Gamecube and GC Animal Crossing disk, of course, and the e-Reader, and a Gameboy Advance, and a GBA/GC link cable. And the cards themselves, of course.

The cards could be used to get all kinds of items in your Animal Crossing village, depending on the card. The amazing thing about the cards is that they seem like they’d be the kind of thing that would have been quickly cracked and turned into a way to obtain arbitrary objects, like the never-released Super Mario Bros. and Legend of Zelda NES items in Animal Crossing, but were in fact only broken fairly recently.

The 11-minute video linked here explains how they worked and how they were cracked, and also links to a GitHub repository with program that can be used to generate your own cards. But Hunter R. has been on this beat for a while, and has two other videos on the subject you can peruse if you wish, on generating custom villagers with cards (12 minutes), and generating Super Mario and Zelda NES items (18 minutes). The villager one is interesting because you can make arbitrary villagers with it, with appearances and names not among the ones included on the disk, although only using the Japanese version of the e-Reader. Even you don’t have the magic combination of gadgets to make practical use of them, they’re interesting watches to understand how the e-Reader worked, and how it was, eventually, exploited.

Fizz over on Metafilter, who regularly makes great gaming posts points us to a Vice article on the conflict, and a Youtube channel of tutorials, made by kids, for kids to use to get past software blockers on school-provided laptops. It shows that school remains a place for kids to learn valuable lessons, just not always the ones that administrators want them to learn, or in the ways they want them to learn them.

I mean, check out how awesome this kid is:
