I passed all the evening and part of the night to build a very basic updater and backtest it with the hosted files, through some scenarios, and it was fully working at the end of the session.
It needs some additional work to be fully presentable, like to have information on the new build, saved game files comptability, the display of the last changes and the progress of downloading / updating, but it is on the right path.
The third-party tool helps a lot since I'm not too much into networking
Today I will work only on the CPS objectives by continuing to process all the possible linking and incomptabilities with the SPM memes and policies, and the backstories.
That's all for now.
