The e-Reader is an add-on product for the Nintendo Game Boy Advance. It has a simple optical card swipe for loading programs off of specially encoded cards. The location of the link port adapter keeps the device from being used with the Nintendo DS. Reader [Caitsith2] has posted instructions for modifying the reader for use with the DS. If you don’t plan on using it with your GBA you can pull the entire board. Once you’ve got the e-Reader switched you can do fun stuff like printing out your own homebrew e-Reader cards.
