Deltarune Chapter 1 Save Editor

A Chapter 1 save editor that detects the format for you

Chapter 1 — the Card Kingdom chapter that started it all back in 2018 — writes its own kind of save file. A Chapter 1 save is 10,318 lines long, while Chapters 2, 3, and 4 share a newer format of just 3,055 lines. They are not interchangeable, and tools that expect the wrong one will either refuse your file or, worse, quietly scramble it.

This Deltarune Chapter 1 save editor handles that detection for you. The moment your file loads, the parser counts its lines, recognizes the Chapter 1 layout, and loads the correct name tables — so Dark Candy shows up as Dark Candy, not as a raw number. Most editors from the 2018 era made you pick the right chapter page by hand before opening anything; get it wrong and you were editing blind. Here there is nothing to pick.

The file itself is friendly to work with: plain text, one value per line, no checksum. That is why a browser-based editor can safely read it, change exactly the lines you touched, and hand back a file the game accepts. Playing the Cyber World instead? Head to the Chapter 2 save editor — same tool, different name tables.

Demo warning: the free Chapter 1 download from 2018 and the free Chapter 1 & 2 demo write a different save format that this editor does not support — demo files are rejected on load. Only saves from the paid full release (Chapters 1-4) work here.

What Chapter 1 players edit

The full release Chapter 1 save exposes everything below — with real names pulled from the game's own tables.

Dark Dollars

Chapter 1's money. Set your D$ to anything you like — max out before a Seam or Rouxls Kaard shopping trip, or keep yourself broke on purpose.

Items & food

Stock up on Dark Candy, Darkburgers, TopCake, SpinCake, LancerCookies, Clubswiches, ChocDiamonds, HeartsDonuts, and ReviveMints.

Weapons & armor

Equip the Spookysword, Brave Ax, DaintyScarf, or the Jevil rewards — Devilsknife and Jevilstail. Armor picks include the Amber Card, Dice Brace, Pink Ribbon, and IronShackle.

Party HP & stats

Chapter 1's party is Kris, Susie, and Ralsei. Raise max HP, attack, defense, and magic for any of them — handy before a Jevil attempt.

Spells

Edit the spell lists for Susie and Ralsei: Rude Buster, Red Buster, Heal Prayer, Duel Heal, and Pacify are all real entries you can add or swap.

Key items

The Cell Phone, the Egg, the Door Key, and Broken Keys A, B, and C — the pieces of Chapter 1's secret-boss puzzle — can all be added directly.

No storage box here: the 72-slot box is a Chapter 2 feature, so Chapter 1 files simply don't contain one. When the editor detects a Chapter 1 save it hides the storage box automatically — nothing to configure.

Jevil: the Chapter 1 secret boss

Jevil is the reason a lot of players come back to Chapter 1 saves at all. He is locked away behind a side quest: collect Broken Key A, Broken Key B, and Broken Key C, have them fixed into the Door Key, and find his cell in Card Castle. He is also genuinely hard — "chaos, chaos" is earned.

Two things make him save-editor territory. First, his rewards are exclusive per run: beat him by fighting and you get the Devilsknife, a weapon for Susie; wear him down with Pacify and you get the Jevilstail, an armor anyone can equip. One playthrough, one reward — the item editor hands you the other. Second, his side quest lives in story flags: which keys you hold, whether the door is open, whether the fight is done. The raw flag browser exposes every flag in the file, so advanced users can revisit those states directly.

While you are in the flag browser, one more advanced curiosity: the Thrash Machine — the mech you design at the end of Chapter 1 — is also remembered through story flags. Tweaking them is power-user territory, but the editor shows you every line.

Chapter 1 save file facts

Everything you need to find, back up, and swap a Chapter 1 file safely.

Know your filenames

Chapter 1 uses filech1_0, filech1_1, and filech1_2 for its three SAVE slots. They sit in the same folder as your later-chapter files.
Find the folder

On Windows: %LOCALAPPDATA%\DELTARUNE. On Mac: ~/Library/Application Support/com.tobyfox.deltarune/. The save file location guide covers Linux and Steam Deck too.
Swap safely

Close the game before replacing any file, keep a backup of the original, and watch out for Steam Cloud restoring the old version over your edit. The how-to guide walks through it.

Slightly damaged file? The editor validates your save before writing and can repair truncated or slightly broken saves. A backup is still non-negotiable.

Frequently asked questions

Does this editor support Chapter 1 saves?

Yes — full release Chapter 1 files are completely supported. Open your filech1 save and the editor detects the Chapter 1 format automatically, then loads the correct item, weapon, armor, and spell names for the Card Kingdom. No manual mode switching is needed.

Why is my Chapter 1 save file so much bigger than my Chapter 2 file?

That is normal. Chapter 1 uses its own save format — 10,318 lines per file — while Chapters 2, 3, and 4 share a newer 3,055-line format. The line count alone tells the editor which format it is looking at, so a bigger file is not a problem and not a sign of corruption.

Will it open my save from the free 2018 Chapter 1 download or the demo?

No. The free Chapter 1 release from 2018 and the free Chapter 1 & 2 demo write a different save format that this editor does not support, and demo files are rejected on load. Only saves from the paid full release (Chapters 1-4) work.

Can I edit whether I have beaten Jevil?

Yes. Jevil progress is stored in story flags, and the raw flag browser lets you flip any flag directly — that part is for advanced users who know which flag they want. The easier route is the item editor: add the Devilsknife or the Jevilstail, the two Jevil rewards, straight to your inventory.

Where is my Chapter 1 save file located?

Chapter 1 saves live in the same folder as the later chapters. On Windows that is the DELTARUNE folder inside local app data, and on Mac it is the com.tobyfox.deltarune folder inside Application Support. Our save file location guide shows the exact path for Windows, Mac, and Linux, step by step.

Why don't I see a storage box tab on my Chapter 1 save?

Because Chapter 1 does not have one. The 72-slot storage box was introduced in Chapter 2, so there is nothing to edit in a Chapter 1 file. When the editor detects a Chapter 1 save it hides the storage box automatically instead of showing you an empty, broken tab.
