That's the point. If the directory gui/pregame was loaded by the xml - like it was before: <script directory="gui/pregame/"/> then one could create a file named mainmenu~MyMod.js and do all sort of scripting therein (for example making proxies of existing functions). But this is not the case anymore for the pregame page. At first glance, this is the only page which changed behaviour. To make a comparison, session.xml is still loading the entire directory gui/session: <script directory="gui/session/"/>   I wish I was!  New release, new work for porting mods. I played my last game in 2023, but 0 A.D. is always in my heart. 

Hey @Mentula Nice to see you're still active! Can't you add a file like autociv like so ~mainmenu.js to extend it ? Else maybe you can wrap the module into something else and use that elsewhere. sounds inconvenient though @phosit

Update: I ended up deciding for "haimaz". I explained my thoughts about it here: https://gitea.wildfiregames.com/0ad/0ad/pulls/8722#issuecomment-135305 I want thank you both for the research and debate, I think the debate itself is also valuable, not just the result. And let's stay on the ground and don't exaggerate the importance of this, after all it is just single term among hundreds in the game. And for the future, let's act in such a way that we'll never have to remove the "No historians were harmed" disclaimer... 

Hi devs and modders, In 0 A.D. 27 and before it was possible to mod the pregame page by adding scripts to the gui/pregame folder. Example of applications are: adding items to the main menu; running startup scripts. Since commit 0fcc4f5fc5 the gui/pregame directory is not loaded anymore, in favour of loading the mainmenu.js file only. It is not clear how mod scripts can run in this page after this change. ✖ It is not an option to override mainmenu.js, mainmenu.xml, page_pregame.xml or other files. This will of course break the compatibility with other mods, as only the last loaded mod will execute the code. Maybe @phosit, do you have an idea? I am pinging you as the author of the change. Thanks.

For now, if you use autociv with ModernGUI, please stack your mods in this order: Otherwise it will crash during gamesetup.  The game is playable like this and you have most of the past features restored to get you back into action! I will gradually work on fixing the other autociv bugs ...
