Tried to add this but unsure if it will stay but here is my advice for the cable feeding.
When reassembling and attempting to feed the antenna cable back under the DS Lite game cartridge reader the cable will likely kink and be difficult to feed through.
Therefore tie a piece of white cotton (or another visible colour) thread tightly around the cable, just below the connector. Then feed the cotton under the DS Lite game cartridge reader and through to the other side. Then gently guide the connector back through by pulling on the white thread and moving either up or down to clear obstacles.
