This is a passthrough card for an NDS, and the G6 lite kit for either the 
NDS or a GBA.  It comes with a USB adaptor to allow you to plug the 
cartridge into your PC and change the files held on it - you can put games, 
movies, music and so on onto it, and play them on the move.

I know there are other cheap solutions out there, so I`m looking for about 
£10 ono delivered for this.

Email me if interested please.

Thanks!
