MedgeNet is a project that restores online features for Mirror's Edge (2009) on PC. It includes a Go server and a Windows launcher that redirects the game to a custom server instead of the retired EA services.

This repository contains the release source for:

• client/ - the Windows launcher and injected client DLL.
• server/ - the Go server for accounts, leaderboards, and ghosts.

Disclaimer: MedgeNet is not affiliated with or endorsed by Electronic Arts.

Full 1:1 replication of original online behaviour is implemented:

• Account and persona creation (for each server).
• Time Trial and Speed Run leaderboard support.
• Ghost upload, listing, download, and playback support.

Support for custom maps or additional behaviour is currently out of scope.

1. Start MedgeNetLauncher.exe as Administrator.
2. Select a local or custom server in the launcher. The release builds in this repo are already configured to connect to the "main" MedgeNet server (associated with the Medge Discord community) which includes speedrun.com level runs in the in-game leaderboards.
   • Alternatively, start the MedgeNet server if running your own instance.
3. Launch Mirror's Edge.
4. Leave the launcher open while playing so it can patch the game process.

The client log is written beside MedgeNetClient.dll.

Client build:

• Windows.
• Visual Studio 2022 with C++ desktop tools.
• Mirror's Edge for PC.

Server build:

• Go 1.25 or newer.
• Administrator/root access if binding HTTP to port 80.
• Alternatively, Docker or another OCI-compatible runtime for the Linux container image. On Windows, use Docker Desktop with Linux containers/WSL 2.

From the server directory:

go run .

To build a Windows server binary:

.\build_windows.ps1

By default the server listens on:

• FESL: 0.0.0.0:18680
• HTTP/FileLocker: 0.0.0.0:80

Runtime data such as the SQLite database, logs and uploaded ghosts are created beside the running server.

The server can also run as a Linux/OCI container. From the repository root:

docker compose up -d --build

It builds server/Dockerfile and stores runtime data in the medgenet-data Docker volume:

• /data/me_server.db - SQLite accounts, personas, leaderboards, metadata.
• /data/me_server.db-shm and /data/me_server.db-wal - SQLite WAL files.
• /data/ghosts - uploaded ghost files.
• /data/session_*.log - server logs.

By default the container exposes the same public ports as the non-Docker server:

• FESL: host 18680 -> container 18680
• HTTP/FileLocker: host 80 -> container 8080

client\MedgeNetClient.sln

Build Release | Win32. The build creates client\dist with:

MedgeNetLauncher.exe
MedgeNetClient.dll
MedgeNetClient.ini

Commandline build:

msbuild client\MedgeNetClient.sln /p:Configuration=Release /p:Platform=Win32

The launcher and DLL read MedgeNetClient.ini:

[Server]
Host=127.0.0.1
Port=18680
HTTPPort=80

Use 127.0.0.1 for a server running on the same PC. For a public or LAN server, set Host to that server's hostname or IP address. HTTPPort must match the server's HTTP/FileLocker port.
