As it is the official is silent, pregmod doing good, refactoring code and adding in new content, for now its limited since they are a lot of changes being mades but its still the most advanced.
Then they are two new project using the general base of FC, as to kinks and settings its unclear yet given to be early in both case.
Free city : Reborn who is only over discord, then I've noir the other in mind ATM, wonder if its not a whole redo over unity or something ?
As to DL, pregmod can be either found over the git, require compilation to be used, so PC/Mac only.
Android there is a web page auto compiling the updated files, its better not to share it a lot since bandwidth could lead to otherwise it getting down.
Since there is no alternative yet to 9c, seem all try did fail over various reasons, it mean the noted two are the main options.
Worry as it is, there no discussion support at all as it is (with developers) there was a limited presence over 9c but now, out of the git who hasn't anything really dedicated to communication exchange, files yes, msg no, even if there could be an add-on or app dedicated to that, my bad, she it has been some time since last crossed it. If right it wasn't good as not compatible with android.
Then, there is this topic, who is a false dead given the game is very much still ongoing..
