Chapter 3 save editor

A save editor built for the Chapter 3 rush

Chapters 3 and 4 launched together on June 5, 2025 as the paid Deltarune release, and Chapter 3 — Tenna's gloriously unhinged TV World — pulled in the biggest wave of new players the series has seen in years. A lot of those players hit the same wall: the save they want to tweak is a plain text file called filech3_0, but most older editors were built for Chapter 1 and choke on it. This Deltarune Chapter 3 save editor doesn't. It was rebuilt for the full release, and the Chapter 3 format is detected automatically the moment your file loads.

Everything runs locally through the FileReader API — your save is never uploaded, there is no account, and the tool works on a phone. If you arrived here from our Spamton save editor, this is the same engine with the Chapter 3 item, weapon, and armor tables preloaded: the toolbar is already switched to Chapter 3, so every name you see is the real in-game name, not a raw ID.

What players edit with the Chapter 3 save editor

Chapter 3 adds its own items, weapons, and armor on top of the classics — all editable by their real names.

Pipis

Chapter 3's strangest consumable — item 35 in the Chapter 3 table. In an unedited game, Pipis is tied to owning the Dealmaker or Puppet Scarf from Chapter 2, or to finishing the Weird Route. The editor skips all of that: drop Pipis straight into your pockets or storage box, in whatever quantity you want.

TV World weapons

The chapter's own weapons are all in the table: Saber10 (23), ToxicAxe (24), FlexScarf (25), and BlackShard (26). Equip them directly on Kris, Susie, or Ralsei — the Puppet Scarf (21) from Chapter 2 is still valid in Chapter 3 saves too.

New armor

Chapter 3's armor entries run from ShadowMantle (23) through LodeStone (24), GingerGuard (25), and BlueRibbon (26) to TennaTie (27). Two armor slots per party member means plenty of room to experiment.

TV World healing

Stock up on the chapter's own consumables: TVDinner, FlatSoda, TVSlop, ExecBuffet, and DeluxeDinner. ReviveMints and TensionGems are still in the table if you prefer the classics.

Money, HP & stats

Set your money to any amount, then tune max HP, attack, defense, and magic for Kris, Susie, and Ralsei. Spell lists are editable too, including UltraHeal.

Key items, rooms & storage

Grab Chapter 3 key items like the ShadowCrystal, PureCrystal, OddController, BackstagePass, and TripTicket, park the overflow in the 72-slot storage box, or set your current room from a curated list of TV World locations.

Chapter 3 save file facts

The boring technical details that make editing safe — worth two minutes before you swap any files.

  • Three slots: filech3_0, filech3_1, and filech3_2 are the three in-game save slots. Most players only ever use the first one.
  • Completion FILEs: filech3_3 through filech3_5 store your post-game completion data.
  • Skip _9: filech3_9 is a continuation file the game overwrites every time you load — editing it is pointless.
  • Plain text, no checksum: a Chapter 3 save is 3,055 lines, one value per line. Edits just work, with no hash to fix afterwards.
  • Shared layout: Chapters 2, 3, and 4 all use the same 3,055-line format, so the editor detects the format and reads the chapter from your filename. Renamed the file? Flip the Ch 2 / 3 / 4 switch in the toolbar so the correct item names load.
  • Where it lives: %LOCALAPPDATA%\DELTARUNE on Windows, ~/Library/Application Support/com.tobyfox.deltarune/ on Mac, and inside the Proton prefix of the full release (app ID 1671210) on Linux and Steam Deck.

Edit a Chapter 3 save in three steps

From filech3_0 to full pockets in about a minute.

  1. Find filech3_0

    Open your Deltarune save folder and pick the slot you actually play on. The save file location guide shows the exact path on Windows, Mac, and Linux. Copy the file somewhere safe before you touch anything.

  2. Edit it above

    Drop the file on the editor at the top of this page — or load the bundled Chapter 3 sample save to look around first. Change money, add Pipis, rebuild your equipment. Everything happens in your browser.

  3. Replace and play

    Close Deltarune first, then put the edited file back under its original name. Watch out for Steam Cloud restoring the old copy, and keep your backup until the save loads in-game. The how to use guide covers the details.

Always edit a copy, never the only version of your save. One spare filech3_0 turns every mistake into a non-issue.

An honest note about Chapter 3 story flags

Every save stores hundreds of story flags — the switches the game uses to remember what you have done. Chapter 2's flags are well documented by now (Spamton NEO's defeat flag, flag[571], is practically community heritage), but Chapter 3's map is still being charted. Community documentation for Chapter 3 story flags is incomplete, and any tool that shows friendly names for all of them is guessing.

So this editor doesn't guess. The flag browser in the Advanced tab shows every Chapter 3 flag by its raw index and value — unknown flags stay unknown instead of getting a confident, made-up label. If you know exactly which flag you want to flip because a guide you trust documents it, the browser will do it. If you don't, leave the flags alone: a mislabeled flag edit can quietly break your route, and honest unknowns beat confident wrong answers.

Chapter 3 save editor FAQ

Was Chapter 3 supported on day one?

Yes. Chapter 3 uses the same 3,055-line save layout as Chapters 2 and 4, so the editor already knew how to read it when the paid release launched on June 5, 2025. Open a filech3 save and the format is detected automatically — no update, no waiting.

Where is my Chapter 3 save file?

Chapter 3 saves are the files filech3_0, filech3_1, and filech3_2 — one per in-game slot — inside the Deltarune save folder. On Windows that folder is %LOCALAPPDATA%\DELTARUNE, and on Mac it is ~/Library/Application Support/com.tobyfox.deltarune/. Our save file location guide has the full path for every OS, including Linux and Steam Deck.

Does it work with the Steam version?

Yes. Steam and itch.io both store saves in the same folder on PC, and the editor reads them identically. Two things to watch: close the game before swapping files, and remember that Steam Cloud can restore your old file over the edited one — let syncing settle before you launch.

Can I edit how many Pipis I have?

Yes. Pipis is a Chapter 3 consumable — item 35 in the Chapter 3 table — and you can add it to your pockets or the 72-slot storage box like any other item. In an unedited game, Pipis is tied to owning the Dealmaker or Puppet Scarf from Chapter 2, or to completing the Weird Route; the editor skips those requirements entirely.

Will my Chapter 2 demo save carry over to Chapter 3?

The editor cannot help there: demo saves use a different file format and are rejected on load. The good news is that the full game reads the same save folder on PC, so demo progress carries over in-game on its own — you just cannot edit demo files with this tool.

Why do Chapter 3 flags show up without names?

Because the community has not finished documenting Chapter 3's story flags yet. Rather than guess and mislabel a flag — which could quietly break your route — the flag browser shows every flag by its raw index and value. If you do not know exactly what a flag does, leave it alone.
