FAQ

Can I use this mod on a dedicated Factorio server?

Yes. Put the zip in the server's mods/ folder and restart.

Do players need the same mod?

Yes - Factorio compares mod lists at connect time, so every client needs the same mod and version as the server.

Where do I upload the zip?

Your Factorio mods folder (single player) or the server's mods/ directory, then enable it in the mods list.

Does this work with Factorio 2.0 / Space Age?

Yes. It targets 2.0 and runs in data-final-fixes, so it overrides the base game and other mods, including Space Age.

Can I edit the generated Lua?

Yes - use Advanced / Custom for exact control, or open the generated data-final-fixes.lua and edit it.

Is this published to the Factorio mod portal?

No - it's a private zip you download and install. You can upload it to mods.factorio.com yourself if you want to share it.

How it works

A Factorio mod is just a folder with an info.json and some Lua. This tool writes both, puts your changes in data-final-fixes.lua (the stage that runs last, so your tweaks win), and packages it as name_version.zip. Download it, drop it in your mods folder, enable it. Want to understand the files? Read how to build a Factorio mod.
