The downloaded version of YAGS: Booty Call from itch.io, by default, is censored. However, if you are of legal age in your area and wish to see adult materials, you can download a game patch that will let you enable nudity in the game.
If you are looking for the patch for Yearning: A Gay Story, go here instead.
Note: Uncensoring is only possible for Windows, Mac, and Linux installations. Android installations cannot be uncensored at this time.
First, you'll need to download the game from itch.io.
Extract the zip file (or zipped tarball).
(Note that uncensoring is not supported to Android at this time.)
Next, find the location where you extracted the game and navigate into the game directory. You should see something like this:
(On mac, right-click on the app and choose "Show Package Contents", then navigate into Contents\Resources\autorun\game.)
Find the downloaded file, and cut it. (Either right-click on it and choose "Cut", or highlight the file and hit Ctrl-X, or Command-X on a mac.)
Navigate back to the game directory, and paste the file. (Either right-click in the folder and choose "Paste" or hit Ctrl-V, or Command-V on a mac.)
You should be prompted to replace the file.
Replace the file and launch the game. You should now be able to play the game without censoring.
