Hello, do you know if I can run Magic lantern on CF card and record to and SD card simultaneously? I dont want to download ML to all my separate sd cards and would rather just download it once.  I do not plan on recording raw at the moment and simply want ML for some of its other features.  Do you know how much space ML usually occupies on a CF card?

I plan on using it on a Canon 5d Mark 3.

Thank You...
