Slate Companion is a companion app for The Legend of Zelda: Breath of the Wild on Windows and Linux, styled after the Sheikah Slate. It reads your save while you play and ticks off shrines, Korok seeds, towers, memories and quests by itself, shows the in-game map with Link's live position from Savage Wind Recomp, and puts a walkthrough, every quest, a cooking simulator, the Hyrule Compendium, armor upgrades, your inventory and your stats in one place. It can also be your Savage Wind launcher: it installs and updates Savage Wind, sets it up with your game files, has all of its settings, starts it straight into the game, and manages your save files. Everything it shows from the game comes from your own copy, built once from your Savage Wind folder.

Caution

No game files are included, and none ever will be: not in the code, the releases, the issues or the wiki. Slate Companion is made to be used with your own, legally obtained copy of Breath of the Wild: the game files in your Savage Wind folder, dumped from your own Switch. On first start it asks for that folder and builds the map, icons, pictures and in-game text from it, on your PC. Please don't post game files, dumps, keys or the built files here.

Important

Made with AI. Every line of code in Slate Companion, every test, the art and this page were written or made by Claude, Anthropic's AI, through Claude Code. A human, devall96, came up with the idea, directs it and tests every build, but no human reviews the code line by line. Who did what has the details. If you don't want to run code written that way, don't run this. As with anything on the internet, you run it at your own risk.

Warning

Early, and tested on two PCs. Slate Companion 0.3 has been run on Windows against real Savage Wind saves and a real Savage Wind install, and earlier versions on Ubuntu. Updating an existing Savage Wind to a newer release hasn't been tried yet (there hasn't been a newer release to update to). Your progress is only ever read from your saves; the Save files screen and Change equipment change saves only when you ask, and back them all up first. It's still worth keeping a copy of any you care about.

Note

Not official. Slate Companion is a fan-made app. It isn't made by, affiliated with or endorsed by Nintendo or the Savage Wind Recomp team. Please don't report Slate Companion problems to Savage Wind: open an issue here instead.

Screenshots

What it does

Your progress, from your save

• Reads your save and ticks things off by itself as you play: all 136 shrines, 900 Korok seeds, 15 towers, the Divine Beasts, memories, and the main, side and shrine quests. Blue means done in your save; anything else you can tick by hand (green).
• Finds saves by itself: Savage Wind (every save profile), Cemu, Ryujinx and Yuzu-family emulators. You can also pick a folder or a save file, or drop one on the window.
• Tracking only ever reads. A save is opened read-only, read in one go and closed, after the game has finished writing it. Only the Save files screen changes saves, and only when you ask (see below).

The map

• The in-game map, built from your own game files at 3 pixels per game unit: sharp at full zoom.
• The game's own map icons for shrines, towers, Korok seeds, stables, villages, the castle and Tech Labs. Done things turn blue, or hide.
• Link's live position and facing from Savage Wind, with Follow Link. Your save spot, your own pins (right-click), and the photo from your album at each captured-memory spot.

Everything else

• Quests & walkthrough: the story chapter by chapter with both DLC packs, all 15 main, 76 side and 42 shrine quests, with the game's own quest log next to step-by-step notes. The walkthrough follows your save: its steps and chapters tick themselves (shrines, towers, towns reached, quests started or finished, Divine Beasts entered or freed), and turning on Tick from my save ticks everything you've already done.
• Shrines: all 136 with a short solution, chest count and the shrine quest behind the hidden ones.
• Zelda Dungeon tab: Zelda Dungeon's own guide, shown as it is inside the app, with a Read on Zelda Dungeon button on every chapter, quest and shrine that opens its page. Nothing of theirs is copied into the app. It goes quiet when you don't use it: the page is closed 30 seconds after you leave the tab or the window, and at once when you minimize or Savage Wind is running.
• Korok seeds: by map square and puzzle type, or the closest to your save first.
• Cooking: the game's own cooking pot (drawn from your game files): drag ingredients in or click them. It uses the game's own rules (checked against 617 real in-game results), every recipe and ingredient, with item icons and the game's descriptions.
• Hyrule Compendium: all 389 entries with the compendium photo and the game's own entry text.
• Armor & upgrades: every piece with its icon, the Great Fairy materials per level, and a shopping list for the levels you want.
• Inventory: everything in Link's pouch with the game's own pictures, names and descriptions: weapons with durability and bonuses, bows, arrows, shields, armor with its ★ level, materials, food and key items, plus rupees, Mon, hearts, stamina and pouch sizes. Link in 3D in what he has equipped, drawn on your graphics card from your own game files (drag to turn him), and your armor set's bonus.
• Change equipment (opt-in): equip and take off, or drag an item onto Link's slot. Loadouts: save sets of gear, preview them on Link and put one on with a click. This edits your save, so it only works while Savage Wind is closed, and backs everything up first.
• Stats on the Adventure log: rupees, hearts, stamina, spirit orbs, Mon, days, Great Fairies, bosses, progress over time and play sessions.
• Guides: Blood Moon, weather, horses, Hestu, the Master Sword, shops and boss tips.
• Search everything with Ctrl+K.

Play Savage Wind (optional)

The Play screen makes Slate Companion your Savage Wind launcher. You choose on the first start, and can turn it off any time in Settings: then it never starts, changes or updates Savage Wind.

• Play goes straight into the game, past Savage Wind Configuration. Starting savagewind.exe yourself, or opening Savage Wind Configuration, works as always.
• Install Savage Wind: downloads the newest release from GitHub, checks it against Savage Wind's signature and every file against its list, puts it in a folder you choose, finds your game files (from another copy of Savage Wind, linked instead of copied where the disk allows, or a dump; or you choose the folder) and sets it up with progress bars: the game files, the game code built from them, the shaders precompiled. None of Savage Wind's own screens are needed.
• Updates: Slate Companion installs Savage Wind's updates itself, the same way Savage Wind's own SW Update does (signature, file list, the same undo journal and lock, a start check, the old files kept until the new version is set up), then sets the new version up. You can go back to the previous version until then.
• Several copies: every copy of Savage Wind on your PC, with a name of your own: which one Play starts, update, set up, go back, or remove from the list (nothing is deleted).
• All of Savage Wind's settings: the same tabs, names, choices and descriptions as Savage Wind Configuration (controls, video, audio, language, saves, game files), plus launch options. Saved to that copy's savagewind.ini, only while the game is closed. What your graphics card can't use (DLSS, FSR 4…) is greyed out, with why.
• Clear Skies: play with Cemu's Clarity look and pick one of its 20 presets, open its mod manager and GameBanana browser, and see when it has an update.

Save files

• Every slot of every Savage Wind copy and save profile, with its picture, date and play time.
• Back up, restore a backup, import a save (Savage Wind, Switch, Ryujinx, Yuzu or a .zip; Cemu / Wii U saves are converted with a port of Savage Wind's own converter, using your game files), import one slot into another, export as a .zip (also converted for Cemu), copy a slot to another slot, profile or copy, and delete one.
• Every change backs the whole save folder up first, into Savage Wind's own backup folder (its Saves tab can restore them too), takes Savage Wind's save lock, and never runs while the game is open.

Light enough to leave open while you play

• A native app (no browser engine inside), drawn on the graphics card (or in software, in Settings) at below-normal priority.
• It does nothing until something changes: a save written, Link moving, you clicking. Minimize it, or click over to the game, and it goes fully to sleep: no timers, no drawing, until you come back. (The map's live position can keep moving in the background for a second screen: Settings.)
• The game files are read once, when it builds; while you play it only shows what was built.

How to install

Windows: download SlateCompanion-win-Setup.exe and run it. It installs for your user only (no admin), adds a Start menu entry, and checks for its own updates when it opens (one small request; you can turn that off in Saves & settings → Updates).

Linux: download SlateCompanion.AppImage, make it executable (chmod +x SlateCompanion.AppImage, or Properties → Allow executing) and run it. On the first start, pick your Savage Wind AppImage (its saves and game files are found from it), and turn on Add to applications to have Slate Companion and Savage Wind in your app menu.

First start: Slate Companion looks for Savage Wind on your PC and lists its game files; press Use these, or Choose your Savage Wind folder… (the folder with savagewind.exe, or ~/.local/share/savagewind on Linux). It builds the map, icons, pictures and text once, in under a minute, and opens. Then it finds your saves by itself. The welcome screen also asks whether you want the Savage Wind launcher (the Play screen).

You need Savage Wind set up with your own game files, the same as for playing it. An extracted romfs folder from your own dump works too.

Link's position, live from Savage Wind

The map can show where Link is while you play, by asking Savage Wind over a read-only connection on your own PC (127.0.0.1:7777). It only reads Link's position, his facing and the time of day: it can't change, move or close the game.

That needs a Slate Companion switch on Savage Wind's start screen, which isn't in a Savage Wind release yet. Until it is, the live position simply stays off and everything else works as normal.

Your data

• Nothing is sent anywhere. No accounts, no telemetry, no ads. It goes online only to ask GitHub for new versions: of Slate Companion when it opens (can be turned off), and of Savage Wind and Clear Skies when you open the Play screen. Downloads happen only when you press Install or Update. The Zelda Dungeon tab loads zeldadungeon.net (with its ads) only while you use it, and up to 30 seconds after; its cookies are kept in the web folder next to your ticks.
• Logs: logs/slatecompanion.log and crash reports (logs/crash-*.txt) in the same folder, with your user name taken out of paths. When something goes wrong, an error window shows the details with Copy details, Open logs folder and Report a problem.
• Your ticks, pins and history are kept in %APPDATA%\SlateCompanion (Windows) or ~/.config/slatecompanion (Linux), next to what it built from your game files. Delete that folder to start over.

Building it

.NET 10 SDK, then:

dotnet run --project src/SlateCompanion

build-release.ps1 makes the Windows installer with Velopack; the Linux AppImage is built by .github/workflows/linux.yml. --screenshots <folder> saves a picture of every screen, and --build-map <romfs> builds from game files without the window. The Play screen's jobs also run from the command line with their progress printed: --sw-install <folder> [<game files>], --sw-update <savagewind.exe> and --sw-setup <savagewind.exe> [<game files>]; plus --convert-save <save> <out> <Bootup.pack> switch|wiiu and --verify-sw <file> <file.sig>.

Who did what

• devall96: the idea, the direction, every decision, and testing every build with real saves and Savage Wind.
• Claude (Anthropic), through Claude Code: the code, the save and game-file readers, the data gathering, the art and the documentation.
