Note: At the beginning the file "Data\System\System.Core" exists with wrong keys....
I advise you to understand, to delete: "Data\System".
Just the "System" folder in the "Data" folder.
I strongly advise you to start the C3 project to understand the code.
To Test the game directly, go to the "Game" folder.
If the "Data\System" folder does not exist, it will be automatically recreated.
Then, if the file "Data\System\System.Core" does not exist, it will be automatically recreated.
Once the "Data\System\System.Core" file is restored, the keys and values do not exist, so the program will recreate them, everything works fine here) -> OK.
Close the program and reopen it -> OK.
Close the program, open the "Data\System\System.Core" file, change the keys, for example add characters to existing keys or change the names of the keys, e. g. "Program", put for example "Prosgramz", in short change the keys.
Restart the program, it will no longer understand anything and so normally it will recreate the keys and values that do not exist, when it is finished, quit, go reopen the file: "Data\System\System.Core".
Normally, you should notice that not all keys and values have been recreated!
He's not doing a good job!
My archive contains two folders: "Projet" and "Jeu"
"Projet" = C3
"Jeu" = Test
