Any way to jump straight to the hardest difficulty level?

[Cthulhu]

I've played the game through twice already but lost my save. Can I skip to the hard part somehow? Is there a cheat code for that? I'd like to beat the game but I don't want to repeat those first two settings.

Thanks in advance.

I see the only person still looking for cheat codes is still me, over 4 years later.

I'm just trying to play online...rip.
