An QT6 based open source frontend for the OldUnreal Unreal Engine 1 games.

This started out as a rough prototype, and then I dropped it for a few years. (oops)

There's a lot of jank in this setup process, but I'm hoping to get this project going and smooth it out in the long-term.

If you're confused or horrified by the code, so am I! We'll get there :^)

Development builds for Linux are built per-commit from the main branch. A set of patched libraries that are currently required are also built.

Simply click on the latest build that was successful (green checkmark), and scroll down to the Artifacts section. Download and place each MultiEd-bin, SDLDrv.so, and OpenGLDrv.so in your UT/System64 folder.

The game has not been tested with these patched libraries, and they're only intended to be used with MultiEd. So make sure to back up the original SDLDrv.so and OpenGLDrv.so!

MultiEd Development Builds

Patched Libraries

Symlink/Place your OldUnreal UT SDK/Development copy into libs/OldUnrealSDK, ensure you have QT6 development libraries installed and build!

There are patch files located in ./patches which will fix some crash and navigation issues. For now you'll have to take the latest UTSDK469d from the OldUnreal project, apply the patch files and compile SDLDrv and OpenGLDrv.

YOU MUST RUN THIS IN XWAYLAND / X11 MODE

This application relies on embedding foreign windows, which isn't supported by QT on wayland. Please run with QT_QPA_PLATFORM=xcb.

On first load MultiEd will generate a MultiEd.ini file in the OldUnreal user data directory. (~/.utpg/System on linux.)

Once that file is created you'll need to make some tweaks (at least on Linux):

• Under Engine.Engine change the various RenderDevice lines to OpenGLDrv.OpenGLRenderDevice

• Under Engine.Engine change ViewportManager to SDLDrv.SDLClient

• Under SDLDrv.SDLClient change StartupFullscreen=True to StartupFullscreen=False

• To resolve any missing icons copy the res folder from this repo into System64/MultiEd.

• Copy the editorres folder from the res folder and copy that into System64.

To the OldUnreal team for giving me early access to their updated SDK.
