Well, I can start working on that.
For example, I know where in sh3.exe the code check, are the sun is below or above the horizon and switch the light on the navigation map.
I will not change that because I'm counting on this to know when the night or day come.
Also, I know where in sh3.exe the code check are the sun is below or above the horizon and switch the illumination of the periscopes graticule.
I had plans to make this for myself to be switchable manually.
Not that I'm so lazy, but I have plenty of activities on different directions, have not come to that, yet.
I will need to search for the light switch for the interior, it may be in the sh3.exe, but maybe is in SH3Controllers.act, I don't know, yet.
And there's no guarantee I'll find it...
