GUIDE TO INSTALL THE SINGLE PLAYER MAPS/MAPPACKS

(taken from THIS POPRE TOPIC)

1) Go to your Populous directory. C:\Program Files\Bullfrog\Populous or C:\Program Files (x86)\Bullfrog\Populous, depending on the operating system you have. I think for Windows XP it still is C:\Program Files\Bullfrog\Populous, newer Windows OSes use C:\Program Files (x86)\Bullfrog\Populous.
2) Unpack the archive file (.zip, .7z, .rar, etc.) you downloaded.

In the folder you copied the files into you will see a "levels" folder and (sometimes) a "data" folder.
In your Populous directory, you will also see a "levels" folder and a "data" folder.

3) Copy the contents from the "levels" folder from your downloaded files to the "levels" folder in the Populous directory.
4) Do the same for the downloaded "data" folder. (If there is one).
5) Run Populous. Your new mappack should run now. Select New Game, loading a game in which you were in the middle of the level will not crash, but use the old map to let you complete the level you were doing. Loading a game in which you were at the solar system works fine.

"I sometimes did all this and did not see the new mappack coming up, so running as admin might be necessary."

VIDEO TUTORIAL:  https://www.youtube.com/watch?v=CfJALepOEF4&feature=youtu.be. "Here you see me installing Katara's Voyage. "
NOTE: "I did not do a discription of the steps in the video using notepad or something, so keep the steps above in mind. Populous won't run in full screen because of low resolution.

Have fun with the maps! Please ask other questions you have. Report any broken links or new links to new mappacks.
Good luck."
