Alexei (natrium42) hacked up a CF card adaptor for a Nintendo DS to connect up a 40GB hard drive, he writes “To get back to hardware development, I decided to do a quick IDE to GBAMP (GBA Movie Player v2) hack. I also took a few pictures for the few people interested in doing this (at their own risk) :) You might not know it, but CompactFlash memory cards use IDE interface; and hence it’s possible to map each IDE pin to a corresponding CF pin. Unfortunately, DS delivers only 3.3V to GBA slot and so an external 5V power supply is required. I used a 11.1V li-poly battery and a DC-DC converter to bring the voltage down to 5V. “ [via] – Link.
