Savefile structure

Pokémon 3D uses a save file structure that everyone can open, read and edit via any plain text editing software (like Notepad++). The game reads the save files every time you enter the Main Menu from the title screen, and writes data to the save files when you use the save feature in the game menu.

Save data is stored in separate folders under the "Save" folder, located where you've installed Pokémon 3D. Usually a save game folder has the same name as the name of the player, but if you try to create a player with a name that already exists, the folder will have a number after it.
(For example, choosing the name "Player" when a folder named "Player" already exists results in a folder named "Player0". Subsequent attempts result in "Player1", "Player2", and so on).
Note that your player name is not determined by the folder name.

In addition, three more files are located in the "Save" folder which contain settings that are shared betweeen save games.

Note: Edit save files at your own risk; if you're not careful you could make the game unplayable or the save files unreadable. It is recommended that you always back-up your save files before editing them.
