It's been 2 weeks, I would hardly call that "abandoned". ML itself has seen months without commit activity. Commit activity isn't even necessarily an indication of actual progress, esp when talking about reverse engineering projects like this one, where much of the work is investigation and research.
All of the code to run the hello world is there in the repo, however, actually running it on camera requires a signed fir (this is a hack after all and you have to "get in" somehow, the way in for ML is through a specially crafted fir file that allows us to execute our own code, creating such a fir requires breaking Canon's encryption)
If you want to know what you need to do to proceed yourself, just read this very thread, there's lots of good information. Especially starting at my reply #36
