No modding possible at all ?

[Akka]

try modding both sets of files.

As I said in the first post, it's already been done. It was, in fact, the first modification made.

After several tries, it appears that modding the borders' colours allows the game to launch, but modding the buildings effect make the game crash.

Either there is a slightly different format in the text files, either the modding isn't happening.
I'll try to do some more tests tomorrow.
