hi there, we have a ds lite with a dstt and 2gb sd card. it has been working perfectly but my son recently put some new games on and it came up with the red menu on the top screen. I reformated the sd card and put on some more games but still the red menu. I bought a new sd card and put new games on but I am still getting the red menu. previously when I added the files to the sd card it was putting on two files for each game, an nds and a .sav (i think!!)

anyone got any ideas?
