The Ninjapass X9 is a Slot-1 MicroSD adapter for the Nintendo DS.

I have written a DLDI driver for the X9 by reverse-engineering its loader. After getting full read and limited write functionality working, the creators of the X9 helped to get write functionality fully working. The purpose of this driver is to provide users of the X9 access to the many great homebrew projects out there.

This driver appears to have been adopted as the "official" DLDI driver by Ninjapass.com. Unfortunately, development is not coordinated with them so I don't know if they've created a fork from my sources.
