I have a brand new DSLink unit for sale. The device is the same size as a normal NDS game cart, and takes microSD (Transflash) media through a slot in the top of the unit. Allows to play all sorts of good stuff on your NDS or NDS Lite. The unit is brand new in the box, and includes instruction manual, mini software cd, and USB SD card reader.

The unit either requires your NDS/NDS Lite to be flashme'd, or requires the use of an Mk4-mini (nopass card). If you need a Mk4-mini, I have one of these as well (new)

DSLink - $45 SHIPPED in the USA
Mk4-Mini - $25 SHIPPED in the USA

Paypal only. PM me if interested!
