On Windows:
- Extract the game... you should see ZAGS.exe, and a "game" folder. Navigate into the "game" folder.
- Ensure you have a zagspatch.rpa file in that folder.
- Download the zagspatch.rpa file from one of the download locations and find it on your computer. (By default it'll be in the Downloads folder.)
- Cut (or copy) that file, and paste it in the "game" directory to override the existing zagspatch.rpa file.
- Restart the game
Don't move ZAGS.exe or do anything to it. You simply need to replace the zagspatch.rpa file with the new downloaded one.
You can also reference the screenshots in the YAGS patch directions for some visual help. You'll need a different patch file (zagspatch.rpa instead of ndpatch.rpa).
(If you're playing on Android, the entire uncensored game is a separate apk file that you'd just download and load onto your device.)
