Game Boy communicates directly with an SD card

July 3rd, 2011, 23:35 Posted By: wraggster

[kgsws] just finished his Game Boy upgrade that allows him to load games from an SD card. Loading a game off an SD card has been done before, but [kgsws] decided to not to use a cartridge-based device. In the end, he threw out all the stops and finished his project by having the Game Boy access an SD card directly.

[kgsws] his project trying to figure out how to put some GPIO pins on a game cartridge, but figured that this would take too much hardware. After looking at the specs of the link port, he realized that it was the wrong polarity. Not to be deterred, [kgsws] realized that there was something like a general-purpose I/O on the Game Boy – the joypad input.
