How to backup saves & file editing

Jump to bottom

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 two 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.

atl_characterProfile_X count from 0 and in-game count from 1, simply reduct by one when trying to find your save file. atl_itemBank is bank tab #1 and atl_itemBank_01 is tab #2, etc. The atl_characterProfile_X_bak files are backups generated by the game used when files disappear or are unable to be loaded. The way they work is that regular files are almost always updating save data, while "_bak" files are previous versions of said data that only update when told to, such as using "Save File" or "Save & Exit" in-game.

If you want to turn on/off Steam Cloud, do the same thing as step 2 and click "Properties...", then disable it in the "General" tab. Here's the website link for accessing the files on cloud.
Steam
ProfileCollections

If you enter a multiplayer lobby and your equipment turned invisible, try right-clicking and unequipping them in the inventory. Though if other parts of your character have been wiped like skills (as a result of multiplayer and not from recent updates, check in singleplayer first!) you will want to immediately close the game without allowing it to save 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. You can use any backup method if anything was lost, for _baks all you need to do is rename them, but first check if they're safe to use!

AutoSaver

If manual backups aren't your thing, _baks and Steam Cloud are unreliable, or you want another layer of safety, then you'll be interested in Marioalexsan's AutoSaver mod! How to install mods with managers or manually.

File Editing

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, it's a human-readable "data interchange format" and is pretty simple once you begin to understand it!

  1. Backuping Saves. First back them up and get to the folder.
  2. Right click on the character or bank file you want to edit. Then open them with your desired program.
    These files don't have extensions so you can't use "Always use this app to open...".

General Notes:

  • Character data can't be edited while playing as them. Edit them before opening the game or open another character first.
    This doesn't apply to Spike's storage which is constant, refresh the UI after saving edits.
  • You can't really use file editing to "exploit", everything you can do is generally doable by a regular player.

JSON Notes:

  • 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.

"_nickName"

(CLICK ME) 
"_nickName": ""

String
Character name. Softer on restrictions for capitalisation and usable characters, but still limited to 18 characters.

"_version"

(CLICK ME) 
"_version": ""

Used by the game for major versions to reset skills upon loading. Editing the value before loading the character prevents it.

"_currency"

(CLICK ME) 
"_currency": 0

Integer
Crowns counter value, accepts ranges from 0 to 1000000 (1 million).

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 consumables are 99 except: Profession Tools, Scrolls, Tomes.
    • Most trade items are 99 except: Angela's Tear, Soul Pearl, Experience Bond, Bronze Arrows.
  • "_slotNumber": Item positions in the inventory, accepts values 0-23/47. It's always 0 if "_isEquipped" is true.
    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.
    • 0: No enchantment.
    • 1: Guardian.
    • 2: Killer.
    • 3: Magical.
    • 4: Precise.

    • 3: Strength.
  • "_isEquipped": Check for equipped gear, duplicate trues causes bugs.
  • "_isAltWeapon": Check for weapons in slot #2, "Lock Weapon" uses slot #1.
    • Despite looking the same, _isEquipped & _isAltWeapon won't work in storage and bug out instead.
