I've been trying to find a way to backup and restore my Pokemon SS save to my flashcart. All the current homebrew methods don't work. The only thing that works is the NDS Backup Plus due to it's ability to update it's firmware. So it is possible through a software fix. I'm in the process of dissassembling the firmware, but it's been awhile and I'm kinda rusty. Anyone who wants to help out just post in this thread. I'll also update this post with my progress. NDS Backup Plus firmware DL page: Here.
