The locales and www folders of the original game are not identical to those in the updated version, so my game was not working. In the original, there are files like "index.html", "save", "icon" etc. I replaced only the "data", "img", and "audio" files from the mod into the original files and also replaced the .pak files in locales. In the mod files, there are no pak.info files, so I left them as they were in original files (in locales). After that, the game started! However, it now loads infinitely.
When I open index.html, I see that the game cannot load Map028.json from the data folder. I could not find the cause of the problem, so I really hope to get a tip about this situation.
P.S. I'm not a programmer and not a native english speaker, so I hope you will understand what I meant.
