Installation

For players

You install Sideload because another mod needs it. On its own it adds no gameplay, no menu and no phone app - it does nothing until a mod registers one, and every developer tool in it is off unless you switch it on.

With a mod manager (recommended)

Install from Thunderstore with r2modman or Gale. MelonLoader and the support libraries are pulled in and placed correctly for you. Nothing else to do.

By hand

1. Install MelonLoader 0.7.3 for Schedule I.
2. Drop Sideload.dll into Schedule I/Mods/.

That is the whole list. Since 1.11.0 the HTML parser, the script engine and its parser live inside Sideload.dll, so there is no second step to get wrong and nothing left behind when you remove the mod.

Upgrading from 1.10.0 or older? You will have AngleSharp.dll, Jint.dll and Esprima.dll in UserLibs/ or next to the mod in Mods/. Sideload still prefers those if it finds them, so an existing install keeps working untouched. Delete them whenever you like.

Requirements

Component	Version
Schedule I	IL2CPP, current Steam public build
MelonLoader	0.7.3 or newer

Sideload does not use S1API. It patches HomeScreen.Start itself, because S1API discovers phone apps by type and Sideload declares them at runtime.

For mod authors

You do not install Sideload into your project. You compile in one file:

<Compile Include="path\to\Sideload.cs" Link="Sideload.Api.cs" />

Sideload.Api/Sideload.cs lives in the Sideload repo. It has zero references - no MelonLoader, no Unity, no IL2CPP interop - and finds the running host by reflection. Referencing Sideload.Api.dll instead behaves identically, at the cost of a second assembly your users have to install.

Either way your mod ships as one DLL and works whether or not Sideload is present. See Your First App.

Settings

Settings live in UserData/MelonPreferences.cfg under Sideload_01_Main.

AppKeys is the only one meant for players, and it is on. It lets an app be reached by a key with your phone still in your pocket - press it and the app comes up ready to use. Only a key the app asked for is read, only where the game would let you take your phone out anyway, and never while you are typing, paused, or in a station, shop or the console. Turn it off and no app gets a key. See Keys and Typing.

Everything else there is a developer tool and is off by default; see Dev Loop and Testing for what each one does.
