How to backup saves & file editing

ATLYSS is an offline game with online support through Steam, so save data is locally stored on your computer and also through Steam Cloud which is supported as well. Unfortunately due to mediocre programming and also early access nature of the game, it is very easy for players to accidentally lose progress or get their characters messed up. This guide will try to show you how to backup your saves, how to repair them if possible, and also how to take advantage of the system for your own benefits.

This page has four points of interest!

Backuping Saves

  1. Open your Steam Library and find ATLYSS.
  2. Right click on the game, hover over Manage, then click browse local files.
  3. Go into ATLYSS_Data, then profileCollections. Optionally you can backup the "Settings" folder as well.
  4. Select and copy all files or just the whole folder.
  5. Create a new folder on your PC, anywhere works, just have it easy to access like using a bookmark.
  6. Paste all of the files in there and update it regularly. You can use any method you like, like multiple folders with dates.
  7. To use these backups, copy all the files you need and go back into ProfileCollections, then paste and replace the files.

To configure Steam Cloud do steps 1-2 and click "Properties...", then go to the "General" tab.
Here's the Steam Cloud Storage for accessing the save files.
Steam
ProfileCollections

atl_characterProfile_X count from 0 then 1 in-game, simply reduct by one when finding your save file. The atl_characterProfile_X_bak files are backups generated by the game used when the save is unable to be loaded. The regular files get updated a lot based on triggers (read below) while "_bak" files are previous versions of said data that only update when the "Save File" or "Save & Quit" actions are used.

If you enter a multiplayer lobby and your equipment turns invisible attempt right-clicking to unequip them from the inventory. If other parts of the character were wiped like skills though (read _version) then you should immediately close the game without causing a save trigger by either clicking X on the ATLYSS window, pressing Alt+F4, or opening Task Manager (Ctrl+Shift+Esc) and ending the task for ATLYSS.exe. Any backup method works if anything was lost like renaming _baks.

If you don't like any of these methods or they're not reliable enough, then you can try out Marioalexsan's AutoSaver mod!

Save Triggers

List of every instance where the game tries to save.

  • Creating a character makes the save file.
  • Using the "Save File" and "Save & Quit" buttons. Only way to generate _baks.
  • Accepting, abandoning, and completing quests.
  • Attuning a world waypoint.
  • Leveling up.
  • Picking up, dropping, or losing items, and sorting inventory.
  • Equipping and unequipping gear.
  • Adding or removing consumables and skills from the hotbars.
  • Unlocking skills, using skill scrolls, and resetting skills.
  • Changing Appearance with the Vanity Mirror.

If it's not listed here, it probably doesn't trigger it.

File Editing

Before starting read Backuping Saves to backup your files and get access to the folder path. Then right click on the character or bank files you want to edit and open them with a text program, these files don't have extensions so you can't use "Always use this app to open..." on them.

The game only loads character save files after entering the main menu or when a character is deleted. This means file editing while playing as the character doesn't work and will be reverted by "Save & Quit", if you don't want to reopen the game you need to load a different character first to go back to the main menu from, or create then delete a character to refresh all saves. Spike's storage reads from the bank files and will reload on UI refreshes thanks to its save triggers.

It is advised you get a text program like Notepad++ and use JSONLint.
To edit save data in ATLYSS we'll need to understand JSON terminology and how to use it.
JSON is a simple human-readable "data interchange format" that is easy to understand with time.

  • Symbols: Braces ({}). Brackets ([]). Quotations (""). Comma (,).
  • JSON starts and ends with either braces or brackets. Properties are written as "name": value.
  • JSON is case-sensitive but mostly format insensitive as long as you follow the structure rules.
  • If there's more than 1 property or value in a container, every entry except the last must end with a comma.
    Rule of thumb: Right-facing braces/brackets don't need a comma while left-facing ones may need it.
  • Warning: JSON does not allow comments like some programming languages with //.
  • Here are the names of the data types we'll edit and basic explanations of their functionality:
    • Boolean: Only has 2 states: false or true. Usually used for disable/enable or off/on.
    • String: Stores characters inside quotations and treats them as text.
    • Integer: Stores whole numbers, including negative values, but cannot contain leading zeroes like 00 or 01.
    • Float: Stores decimal numbers and is often used for percentages, multipliers, or precision values.
    • Array: Bracket containers used for storing lists of values.
    • Object: Brace containers used for storing properties and values together.
      • Arrays and Objects can nest other Arrays and Objects.

Nested Array; String, Integer, Boolean, Object
This is the first thing that applies to both atl_characterProfile_X and atl_itemBank, so I'll explain it carefully.

  • "_itemName": Item identifier and display name. What's seen in-game is the ID.
  • "_quantity": Item stack amount.
  • "_maxQuantity": Item stack limit, this value cannot be edited and the game will auto-correct it.
    • All equipment have a maximum of 1.

    • Most trade items are 99 except: Angela's Tear, Soul Pearl, Experience Bond, Bronze Arrows.

    While the inventory sorts left to right, the files sort from top (oldest) to bottom (newest).
  • "_modifierID": Item enchantment modifier, only works on equipment.
    Exotics can be enchanted to Legendary inside _heldItemStorage but _inventoryProfile will remove it, still no bonuses.
