If your not really interested in modding the game yourself...
Do a full install from the FFVII game disc.
Follow the instructions on getting started.
Replace your existing folders with the links below.
The folders have the latest mod version...
The Folders need to be replaced in this order
FFVII Folder (C:\Program Files\Square Soft, Inc\)
Data (C:\Program Files\Square Soft, Inc\Final Fantasy VII\)
Movies (C:\Program Files\Square Soft, Inc\Final Fantasy VII\)
As the size of the folders get ever bigger, I will separate the directories even further...
