You send me your save file(s) per E-Mail or Google Drive
I will mod your save game(s) for you. There is a list of applicable cheats on the homepage of Save Wizard, so you can take a look there which cheats are available for the individual games. You can find them here: https://www.savewizard.net/
After I have finished modding your save games, you will get them back per e-mail or I will upload it to you to your Google Drive.
As I wrote, you can send me the save games files to your e-mail which is: [email protected]. This is also my PayPal address in case you decide to purchase the slot from me.
