Add an Fm Radio to Your Nintendo Ds
This little add-on for the Nintendo DS (and DS Lite) lets you listen to the radio while getting your game on.
The $14 Dragon NDS Lite FM Radio Converter plugs into the front expansion port on the DS, and gets its power from the DS internal battery. This means it’s really compact, but will drain your battery a bit faster than usual. The adapter is available from Hong Kong importer, Brando.
