UFO 50 Setup Guide

Required Software

• UFO 50 for PC
• The UFO 50 APWorld (bundled with MultiworldGG)

Installation

Automated Installation

1. Unless you use MultiworldGG: Place the UFO 50 APWorld in your custom_worlds folder.
2. Create a new folder for the modded UFO 50 installation (don't put it in your normal UFO 50 install folder). Do not manually copy anything into this folder.
3. Open the MultiworldGG Launcher and click on the UFO 50 Client.
4. When it asks you to select a folder for the mod installation, select the folder you created in step 2.
5. When it asks you to locate the UFO 50 executable, navigate to your UFO 50 .exe file and select it.
6. To launch the game, run the UFO 50 Client from the MultiworldGG Launcher.

Manual Installation

Do not follow these steps if you are doing the Automated Installation above.

Extra required software:

• A way to apply .bsdiff4 patches, such as bspatch.

Steps:

1. Copy all of your UFO 50 files to a safe location.
2. Extract all files from ufo_50_archipelago.zip into the same directory as the files extracted in the previous step.
   • This should include, at least, ufo_50_basepatch.bsdiff4 and gm-apclientpp.dll.
3. Delete steam_api64.dll and Steamworks_x64.dll.
4. If you don't have original_data.win, copy data.win and rename its copy to original_data.win.
   • By keeping an unmodified copy of data.win, you will have an easier time updating in the future.
5. Apply the ufo_50_basepatch.bsdiff4 patch using your patching software.
6. To launch the game, run ufo50.exe.

Downpatching UFO 50

As UFO 50 is a game that is still receiving updates, periods of time between new official patches and the mod being updated will exist. Therefore, the user may end up having to either wait for the mod to be updated or use an older version of the game in order to play. You can check which version of UFO 50 the mod targets in the patch releases page.
