Yah, if you grab Idol Ninja's compile of Gentlemen of Steelport (GoS) for Sr3 in it there is part
of the base pack a mod for cheats, that also doesn't flag your game saves (feature).
If installed, part of the extra cheat pack is now a cheat to change time of day. It might take several toggles,
but you can end up in day, night, or other periods in between. Random toggle . Just exit the cheat to see if your finally
in time of day you actdually want.
I use it here all the time as I prefer skulking around at night. Bright neon lights and all make me happy/
Used as is with that pack will not flag your save as cheated, unless it was flagged before . I understand it can't
remove that flag but if it wasn't flagged already then the saves wont be flagged forever afterward. SOme sort of magical rubber is included.
So problem solved.
Oh, and I don't get what you said in your post. In my8 games, if it is daylight , it never changes. Until the game reloads
or you die and the session reloads. Then the time of day can change. It is random in this game. There is NO
time in the game while playing. (not affecting the light anyway). So if dark, it stays dark, if light it stays that way.
I can leave the game running for days in the dark and it never turns to daylight or vice versa unless you reload.
