I recently purchased a new ITouch DS & 4GB Micro SD (Transcend). When first put into my Nintendo DS it read: No “boot.xxx” file found I asked a friend to try to download some software into it. I then tried to reinsert it into my DS. Again it read: No “boot.xxx” file found I am not sure what to do next. Should I copy the software onto my computer, delete it from the SD, somehow format the SD and reload the software?
