Hyland Helper

Hyland Helper adds a native-style companion app to the Schedule I in-game phone. It reconstructs the mixes discovered in your current save, shows ingredient chains and economics, lets you keep recipes locally, and connects to the optional Hyland Helper mobile app.

Features

• Browse Community Recipes.
• Reconstruct arbitrarily long one-ingredient-per-step recipe chains from your current playthrough.
• Filter discovered mixes by base product and effect.
• View effects and request sell price, cost, profit, and margin.
• Keep selected in-game recipes in Saved Recipes.
• Send recipes from the Hyland Helper mobile app to Phone Recipes in-game.
• Receive optional incoming-only Advisor Dispatches.
• Pair, manually sync, and unlink directly from the in-game phone.

Installation

Installing with Thunderstore Mod Manager or r2modman is recommended. The declared dependencies install MelonLoader and the tested S1API Forked release automatically.

For a manual installation:

1. Install MelonLoader 0.7.3 for Schedule I.
2. Install S1API Forked 3.0.6, including its required Mods and Plugins files.
3. Copy these files into the game's Mods folder:
   • HylandHelper.BridgeMod.dll
   • HylandHelper.PhoneTile.dll
   • hylandhelper_icon.png
4. Start Schedule I, open the in-game phone, and select Hyland Helper.

Typical Steam path:

C:\Program Files (x86)\Steam\steamapps\common\Schedule I\Mods\

Both Hyland Helper DLLs must come from the same release.

Mobile pairing

Pairing is optional. When the tile shows a pairing code, enter it in the Hyland Helper mobile app's Live Sync flow. Pairing is scoped to the active playthrough. Unlink revokes the connection and starts a fresh pairing flow without modifying the game save.

Network and privacy disclosure

This mod connects to https://hyland-helper-backend.vercel.app because network access is required for Community Recipes, recipe economics, optional mobile Live Sync, Phone Recipes, and Advisor Dispatches.

Community and economics requests send only the recipe data needed for the requested result. If you explicitly pair the companion app, the bridge sends bounded read-only snapshots and liveness messages for the active save. Those may include an opaque save fingerprint, app/device/profile scope identifiers, game/mod versions, rank and in-game time, money, product/mix data, inventory, and owned-property/layout summaries. A revocable bridge token is stored locally and protected with Windows CurrentUser DPAPI. The mod does not send your Steam login credentials.

The mod stores its own cache and status files under:

%USERPROFILE%\AppData\LocalLow\TVGS\Schedule I\HylandHelper\

See the MadJag Studios privacy policy.

Read-only promise

Hyland Helper never writes Schedule I save or game state. It does not change stations, inventory, properties, NPCs, or the built-in Messages app, and it does not automate mixing. Save Recipe and recipe publishing affect only Hyland Helper's own local or paired-app data.

Compatibility

Tested with:

• Schedule I 0.4.5f2 (IL2CPP)
• MelonLoader 0.7.3 Open Beta
• S1API Forked 3.0.5 and 3.0.6 IL2CPP MelonLoader releases

Game or framework updates may require a Hyland Helper update.

Changelog

0.4.0

• Updated for the Schedule I 0.4.7 Special Customers update. Property layouts didn't change, so layout apply and app layout import work on 0.4.7 saves.
• New: QR pairing. The pairing screen shows a QR code above the pairing code. Scan it with your phone camera, or with Scan QR in the Hyland Helper app once its update is out. Typing the code still works.
• Fixed: applying a layout to the Motel Room, Sweatshop or Sewer Office was refused because of the wall clock.
• Fixed: layouts deleted in the app no longer get stuck on "Loading this layout".
• Fixed: layout sync could stay disconnected after restarting the game, even though the app showed the PC as paired.
• If a layout apply was interrupted and can't safely continue, it no longer blocks the property. The Layouts screen shows what happened and lets you dismiss it. Dismissing doesn't refund or remove anything.
• Layout apply only runs on game versions this mod has been checked on. On a newer game version it asks you to update the mod.
• The pairing code is no longer written to the game log.
• Requires S1API 3.2.1.

0.3.1

• Fixed applying a layout created in the Hyland Helper app or on hylandhelper.com to an owned property. Such layouts carry the app's property name, so the mod incorrectly reported the target property as one you don't own and the apply could not start. The mod now resolves app property names to the in-game property, so app- and website-authored layouts apply correctly. Layouts captured in-game were unaffected.

0.3.0

• Updated for Schedule I 0.4.6f13. The bundled layout reference was pinned to 0.4.6f11, so on the current game version the mobile app reported "Layout data update required" and property layout import was unavailable. Layout data was re-captured on 0.4.6f13 (the property grid geometry is unchanged from 0.4.6f11), so layout import is available again on the current game version.
• In-game Layouts screen in the phone tile: browse captured property layouts and use Save Layout to capture your current build's live state.
• Personal layout library syncs through the backend, with load-time reconciliation of interrupted layout jobs and auto-refund of orphaned recovery jobs.
• More reliable save reading and layout capture, including structural objects read from real saves.

0.2.1

• Property layouts now import into the mobile app's Layout Studio correctly.
• More reliable save reading on Schedule I 0.4.6f11.
• Fixed a false "Backpack unavailable" notice on saves with no backpack.
• Phone tile: the "Unlinking" message clears after you unlink, and the current session tile turns gold when connected.

0.2.0

This is the first public package after the old Nexus v0.1.2 release. It includes the previously prepared v0.1.3-era synchronization and reliability work as well as the new Sideload phone experience.

• Adds a scroll-safe embedded Sideload 1.3.0 UI with responsive recipe catalogs, filters, details, pairing, and phone controls.
• Reads recipes from the active Schedule I 0.4.6f11 save and merges supported mixes discovered live before the next manual save.
• Keeps optional mobile Live Sync, Phone Recipes, Advisor Dispatches, manual sync, unlink, Community Recipes, and on-demand economics available from the modern UI.
• Retains the restart-scoped S1API fallback through required S1API 3.1.4 when Sideload is missing, old, or incomplete at startup.
• Carries forward faster bounded adaptive sync, foreground Phone Recipe refresh, supported live rank/day/property/money capture, improved Advisor Dispatch accuracy, and committed-layout change signals.
• Reduces idle parsing, scanning, and redundant work while improving pending command and delivery-result recovery.
• Preserves v0.1.2 playthrough isolation, save-generation validation, and pairing recovery protections.

The package requires MelonLoader 0.7.3 and contains only HylandHelper.BridgeMod.dll, HylandHelper.PhoneTile.dll, the runtime icon, and release metadata. Third-party dependencies are declared rather than bundled.
