I put that there. For the needs of the review and in order to unlock all the functions of the game, I had to edit the save file to have unlimited money and XP, but also skill points. Here is the manipulation for those who are interested.
Find your backup file in C: \ Users \" Your username "\ AppData \ LocalLow \ Red Dot Games \ Car Mechanic Simulator 2021 \ Save
There is a file named profile0.cms21 which corresponds to the first save of the game. It must be opened with Notepad or another text editor like Notepad ++.
For skill points, it is the “points” value which is just before upgradeForMoneyData that must be modified. If you want 100 skill points, you have to put 100. You can then assign them ingame.
There you are, you know everything. But between us, the game is quite easy and the progression fast, so don't overdo these Car Mechanic Simulator 2021 cheats, and fully enjoy the game on Easy mode if it's too hard for you.
