tiggerlator, thanks for your great advice. But ıf you dont mind, i want to ask something to make things clear..
I had Firmware 1.4.2 (i think) on my nintendo dsi... and my card was working on that version..
if i hadn't update my dsi firmware, this card would boot with it, then when its open, i would update the card from cards software and update the card; then update the firmware...
But; i updated the firmware to 1.4.3 and this card is now "useless" for my nintendo dsi.. right???
is it like burning a dvd on pc and trying to run it on ps3 ???
i mean yes i updated to 1.4.3 , now the card is useless...
but when i download the newest files and put them into that card from pc... why doesnt it work? whats the main point there?
do i think right? can you please tell me a little more if you have info about that?
then ill try to find a ds lite and solve this.. thanks a lot by the way.. great help
