As a result of the leak, Waninkoko is now quite upset, and announced that he no longer plans to work on the project- meaning very likely no new versions of it will come.
To quote: Backup-Loader is now an abandoned project. Congratulations, enjoy that version that has lots of bugs (yes, lots of bugs are not fixed).
How to use it:
1) Patch the iSO with the .exe that came in the download
2) Install the CiOS on your Wii
3) Install DVDX. Go to Advance and choose 249
4) Install Wii Loader
5) Burn the patched iSO with ImgBurn
6) Run the loader
