🎮 What is Gameroom

Your games are scattered across Steam, Epic, Battle.net, EA, Riot, Xbox, standalone launchers, emulators and loose folders. Gameroom brings them all into one library that looks like a console home screen, and takes care of what stores don't do for you:

• It knows what you're playing. Games are recognized even when you start them from a shortcut, their folder or another store, and your playtime is counted minute by minute.
• It backs up your saves while you play, and gives them back after you reinstall a game or Windows.
• It shows Steam achievements for your games, even the ones you didn't install from Steam, with an in-game notification when you unlock one.

Every game is yours, and always will be

That's the project's motto, and it's meant literally:

• No store, no ads, no subscriptions. Gameroom doesn't sell anything and doesn't need an account.
• Your data stays on your PC. Your library, playtime and save backups are stored on your own computer, in open formats.
• Your cloud is yours. If you want cloud saves, Gameroom keeps them on your own free Supabase server, not on ours. Nobody else can access them.
• Open source (MIT). You can read it, change it and share it. Even if the project disappeared tomorrow, your copy would keep working.

Inspired by Playnite, rebuilt from the inside

Gameroom started as a fork of Playnite, the excellent open source library manager by Josef Nemec, and is a revamped version of it:

• A new console-style interface, with a page for every game.
• New features: live game detection, save backups, Steam achievements with notifications, accounts with your own cloud, and automatic detection of installed games.
• Still compatible with Playnite extensions and themes.

It installs side by side with Playnite without touching it: it uses its own data folder and, on first start, offers to import your Playnite library.

Gameroom is available in English and Spanish.

⚙️ How it works

Your library. Gameroom keeps your library on your PC, in %AppData%\Gameroom:

• Games and metadata: in Playnite's format.
• Gameroom's own data (sessions, backups, achievements, save locations): in gameroom.db.

Stores are connected through extensions (for example, the Steam one). Anything without an extension is found by Gameroom itself.

Finding installed games. On startup, and every 20 minutes, Gameroom looks for new games in:

• Windows' installed apps.
• Launcher manifests.
• Xbox packages.
• Desktop and Start menu shortcuts.
• The top-level folders of your drives.

Something only counts as a game with strong evidence:

• A launcher registration (Steam, Riot, Battle.net, EA, HoYoPlay, Epic, Xbox).
• Game engine or Steam API files in its folder.
• A repack installer.

Every app it checks is remembered: games you remove from your library don't come back, and leftovers of uninstalled games (whose folder is gone) are ignored.

Live detection and playtime. Every few seconds Gameroom compares the running processes with:

• Each game's executables.
• Each game's install folders.

While a game is running, playtime is added every minute and the session in progress is saved. If something unknown looks like a game, Gameroom offers to add it and keeps the playtime of that session.

Save backups. To find where each game keeps its saves, Gameroom uses:

• Known paths of Steam and Steam emulators (Goldberg/GSE, CODEX, RUNE, EMPRESS, OnlineFix…).
• Unity data (LocalLow\Company\Product) and Unreal project folders.
• What it learns while you play, by watching which files the game writes.

It then makes versioned ZIP backups while you play and when you quit.

Achievements. Definitions (name, icon, rarity) come from Steam's public API, no key needed. Your progress is read from the Steam client (appcache\stats) and from Steam emulator files. Games that weren't installed from Steam are looked up on Steam by their AppID or by name.

Cloud (optional). Once you connect your Supabase server:

• Every save backup is uploaded to a private folder of your account.
• Opening Gameroom on another PC downloads the backups that are missing there.
• The session is stored encrypted with Windows DPAPI.

Privacy. Gameroom only connects to:

• Steam's public API and metadata services, for artwork and achievements.
• GitHub, to check for updates.
• Your own server, if you set one up.

There's no telemetry and no mandatory account.

📥 Installation

1. Download GameroomSetup-x.y.z.exe from Releases.
2. Run it. It installs for your user and doesn't ask for administrator rights.
3. On first start, if you use Playnite, Gameroom offers to import your library, extensions and themes without changing Playnite.

Requirements: Windows 10 or 11, and .NET Framework 4.6.2 or later (already included in Windows 10 and 11).

Gameroom checks for updates on startup and every 4 hours. You can also check by hand with Check for Gameroom updates in the Start menu.

☁️ Your own cloud (Supabase)

What it's for

It gives you a Gameroom account and cloud saves: every backup of your saves is uploaded to your server. If you switch PCs, reinstall Windows or your drive dies, you get your saves back just by signing in.

Why your own server

Because your saves are yours:

• Gameroom has no servers. It can't see, sell or lose your data, and it doesn't need to charge you to keep it.
• Everything goes to a Supabase project you create, for free.
• Every account can only read its own saves, enforced by the database's row level security (RLS).

Supabase's free plan is more than enough for you, or for your family and friends.

It's optional. Without a server, everything else works exactly the same: detection, playtime, local backups and achievements.

Setting it up (5 minutes)

1. Create a free account and a project at supabase.com.
2. In the project, open SQL Editor, paste the contents of supabase/setup.sql and click Run.
3. Click Connect at the top of the dashboard and copy the Project URL and the publishable key (sb_publishable_… or the anon key).
4. In Gameroom, go to Account, paste the URL and the key, and click Connect. Then create your account.

The full guide, covering email confirmation, sharing your server and free plan limits, is in docs/SUPABASE.md.

Important

Never put your secret key (sb_secret_… or service_role) into Gameroom, and never share it: it gives full access to your project. Gameroom refuses it if you paste it by mistake.

🛠️ Building from source

Requirements:

• .NET SDK, which can be a portable one (for example in D:\dotnet).
• Visual Studio Build Tools 2022 with MSBuild.

You don't need the full Visual Studio.

.\build\dev-build.ps1 -Restore   # first time: restores NuGet packages
.\build\dev-build.ps1            # builds the app into build\Debug
.\build\dev-test.ps1             # builds and runs Gameroom's tests

Where things are:

• Gameroom's code: source/Playnite/Gameroom (services, cloud in Cloud, updates in Updates, installed games in InstalledGames).
• User interface: source/Playnite.DesktopApp (Home and Account views, the game page, and styles in GameroomResources.xaml).
• Tests: source/Tests/Gameroom.Tests.
• Texts: source/Playnite/Localization/Gameroom (English and Spanish).

Other details:

• With the GAMEROOM_DEV_INSTANCE environment variable set (to any value), a development build can run next to an installed Gameroom.
• Icons and splash screens are generated by python build\branding\generate_branding.py (requires Pillow).
• gameroom:// links open parts of the app, for example from a shortcut or a script: a game's page, its achievements, sessions or save backups, play statistics and settings. See Links and shortcuts.

Publishing a release

1. Raise GameroomVersion in source/Directory.Build.props.
2. Run .\build\publish.ps1 -Notes "- New thing 1`n- New thing 2". It needs Inno Setup 6 and GitHub CLI after gh auth login.

The script builds Gameroom, creates the installer and publishes it as a GitHub release, which is where Gameroom looks for updates. -SkipUpload only creates the installer, and -Prerelease publishes it for the beta channel only.

Making your own build? Change ReleaseChannel.GitHubRepository in source/Playnite/Gameroom/Updates/GameroomReleases.cs, so your users get your releases.

Known limitations

• The new views exist in desktop mode only. Fullscreen mode uses Playnite's theme with Gameroom's colors.
• Emulated games started outside Gameroom aren't detected live, because the running process is the emulator.
• The achievement notification can't be drawn over games in exclusive fullscreen. It works in windowed and borderless fullscreen.
• A detected game whose internal name differs from its store name (for example Endfield instead of Arknights: Endfield) may get no cover. Rename it in Edit and download its metadata again.
