I don't know why but i tried again this morning to see if it was working and by surprise it worked !
But when i took the microSD and putted it back it didn't worked... =(
So i think it's half-dead xD
Well here's the problem my NDS doesn't detect the cycloDS i thought it was the microSD but no i tried with two different microSD and it was still undetected... =(
I have one of the first Cyclo so is it dead ?
