Based on Yifan Lu's research, we're working on an open source content manager.
I can't release it now for two reasons : it doesn't have GUI (it is not really necessary but it's more user-friendly) and it may have bugs that break your data.
Currently the program can only transfer applications, games and save-data (no music/video/photo and full backup/restore, but it's planned)
So I come here to find some beta-testers who have a Linux system (porting to other platforms is planned), have a minimum of programming knowledge and want to help me to make this program safe and useful.
Just PM me and I'll send you the current sources (but don't leak please ).
You have to compile it by launching the 'build.sh' little script as root user, then start 'oicma' as root too. But before that I recommend you to make a backup of all your data using the official CMA.
Thanks for helping
Edit: I forget to say that testers need to install libusb1-dev and libxml2-dev
Edit2: libtool is also needed
EDIT3: Now it's closed, I have a dozen of testers so it will be enough
