Magic Lantern starts work on way to `enhance` Canon EOS R feature-set
(Digital Photography Review)

An example of the Magic Lantern software running on an EOS DSLR The group that provides Canon users with programs to expand the feature set of their cameras has begun cracking the new EOS R mirrorless firmware. Beta firmware from Magic Lantern is said to be in the test stages, and if it follows already existing Magic Lantern software, it will add new display overlays, uncompressed raw video, focus stacking and even the chance to load games on to the camera. Magic Lantern doesn´t replace the firmware already loaded onto the camera by Canon, but is extra software that runs alongside it to add additional features. Many users will perhaps hope that full-sensor 4K video will be added, though the consequences of the camera using the whole sensor area for extended recording is yet to be discovered. Andrew Reid from EOSHD shows a video of an experimental firmware probe successfully taking control of the camera system - even if to just show a green screen. This, he says, is good news, as it means the Magic Lantern code `was able to execute on the EOS R as normal´ and `which demonstrates the possibility to change camera registers and execute code on the main processor.´ Obviously more work is needed, but the first steps of cracking the file format and encryption seems to be underway.
