OK follow these steps:
1.Download Yamp and all the patches you want from the first post of this topic
http://forums.qhimm.com/index.php?topic=5124.02.Extract all the files
3.In the YAMP folder make a folder called 'patches'
4.Copy the .srb and .txt files from each of the patch folders and paste the files into the new 'patches' folder you just made
5.Copy the contents of the YAMP folder (not the actual folder) to your FF7 directory (defult= C:\Program Files\Square Soft, Inc\Final Fantasy VII)
6.Run the file called install, If you use Vista, run it as an administrator (Right Click and choose this option)
7.Thats IT! Like Makubex said don't rename the Backup_FF7.exe because that is a copy of your old .exe, just run the game by clicking on the new FF7.exe
Simple!
