[!IMPORTANT] re:Blue is an unofficial project

re:Blue

re:Blue rebuilds Blue Dragon as a native application through static recompilation, translating the original code into something your machine runs directly rather than emulating a console around it. That opens the door to things an emulator cannot reach: higher frame rates, modern resolutions, and real mod support.

How to Install

Download latest release for your platform or build yourself

1. Blue Dragon shipped on three DVDs, and you will need a disc image of each one from your own copy of the game.

2. Run the executable. A setup wizard will guide you through the rest. You will be asked to point it at each of the three disc images in turn, and it will check each one before letting you continue. Once you pick where to install, the program copies itself there and restarts from that location, so you can delete the folder you extracted the zip into.

3. Pick a graphics quality preset. The wizard copies the game files out of the discs, and you are done. You may also install DLC from this installer or from the main menu under the config menu

The wizard only needs to run once. If something later goes missing from your install, launching with --repair reopens it on your existing install and copies back only what it needs.

FAQ

Where is my save data and configuration stored?

Everything lives under the folder you installed to:

• Saves and settings: profiles\default\
• Your configuration file: profiles\default\reblue.toml
• Game files copied from your discs: game\
• Mods: mods\

I want to update the game. Will I lose my save data?

No. Copy a newer build over your existing installation and your saves, settings, and mods are left alone. You do not need to reinstall or point the wizard at your discs again.

How do I install mods?

Use the mod manager in the config menu. It accepts a mod folder or a zip file and puts everything in the right place for you

Can I keep more than one set of saves?

Yes. Each profile is its own folder under profiles\, holding that profile's saves, settings, achievements, and DLC toggles. Launch with --profile <name> to pick one, and anything but default starts out fresh.

Building

re:Blue builds with CMake and vcpkg against the ReXGlue SDK.

cmake --preset win-amd64-release       # or linux-amd64-release
cmake --build --preset win-amd64-release

Presets cover win-amd64, win-vk, linux-amd64, linux-arm64, mac-amd64, and mac-arm64, each in Debug, Release, and RelWithDebInfo. A win-amd64 preset builds both the DX12 executable (reblue.exe) and the Vulkan one (reblue_vk.exe), and a win-vk one builds the Vulkan executable alone. As with running the game, building requires the files from your own copy of Blue Dragon.
