I'm not a developer but I do dabble and I was able to install Kodi 19 (Matrix) stable in an ubuntu virtual machine and change some things to see Cinemavision boot. I was using the 1.1.1 version that I have running on my Kodi 18.0 machines as the base since I don't have any with the newer 1.1.1a10-a12. By changing some of the requirements, updating import paths, and changing some lines regarding decode("utf-8"), and updating the included_packages\hachoir to 3.1.3, it loaded and I was able to play a basic sequence that came with Cinemavision. It is far from being a successful upgrade and I don't know what else I broke getting it to run but there is hope! and it doesn't seem that impossible! I did this during a weekend so the real developers should be able to get something together quicker since they already understand the intricacies of their own coding and development better than I do!
