There are typically two distinct locations users must be aware of regarding the CODEX release:
This can be done by copying the remote folder from the CODEX directory and pasting it into the EMPRESS directory. You then need to open the steam_emu.ini in the game folder, find the numeric ID in the new save folder, and assign it to the #AccountId line.
This subfolder contains your actual gameplay progression files, including your profile, unlocked cars, map progress, and festival accolades.
Launch the game. The main menu should now show the new credits, level, or garage associated with the save you installed. If the game starts from the very beginning again, the Account ID in the steam_emu.ini file does not match the ID of the save file you installed.
