i have the original top toy(black and white) dstt, and a ds light. i had 2, but i gave away my working one and recently decided after about a year away from the ds scene that i really missed some games and wanted to try a few new ones. i bought a micro sd card 2gb and put the firmware on the card. none of the new games worked so i tried mario kart and moon.. they worked and work fine, but nothing else will work. it loads and then freezes about 80% of the way in. i have the two games in the root directory, so i make a sub directory and tried putting some roms in there to no avail... i am using a macintosh (powerpc emac running 10.5 leopard) to copy the files over not that it shoudl make a difference. can soemone walk me thru this and tell me what (im sure) is the obvious mistake i am making!!??? thanks!!
