Ok, I have both a M3 Simply and a SCDS but only 1 microsd card. So this last week ive been erasing the software on my card that went to the M3 and put on SCDS software and vise versa. Then today my m3 Simply wont boot on my DS Lite . When its in my slot-1 my DS just goes to the normal menu just like if you had no flashcart in it. What is wrong?? What did i do?? What can i do to fix this? (also my SCDS still works, i think.) Thank you!!
