Like Pure Farming allows the editing of backup files with a text editor to take a little more money. The point on the variables to modify in youtube video.
Here are the steps to follow briefly:
Start a game in sandbox mode
Make a backup
Quit the game
With your file explorer go to this location: C: \ Users \ \ AppData \ LocalLow \ Techland \ Pure Farming 2018 \ Game Save
Go to the directory of the backup to edit the files “SavePF0.psav” and “AdditionalInfoPF.psav”
Open them with Notepad or any other text editor
Do a search (ctrl + F) on the value of your portfolio (default 25000) and add a few zeros to this figure
Back up your files and restart the game
You are rich as Croesus!
