Any possible way of 'cheating' ?

[Puff]

Well, I hate it when I want to light up the place / make some light and I'm out of tinderboxes or oil.
I've tried searching for cheats made by the development but found none and trainers are rejected by the game itself when it detects them. I get some error saying that it can't run it whenever I try to play with a trainer.

My question is... or are:
Is it possible to use cheats/trainers to work without restriction?
Is it possible to change a setting from the game folder's files to add more tinderboxes or other items?

I just want to create a 1800 atmosphere by lighting up the place, for example when I was working in the laboratory of the castle next to the wine cellar. One more thing: I'm stuck where the stairs felt and only have 3 of the 4 substances needed for preparing the acid... how can I get out?

Thanks.
