I have just obtained a NDSTT card for my nephew along with a whole bunch of games (.nds files). I put a 2GB card with the Ttmenu folder and the ttmenu.dat file I downloaded from ndstt.com v1.07. I have been reading in other forums that there should be a .sys file also but I didn't get that in the zip folder when I downloaded it? Where do I get it from? Thanks for any help I get.
