|> Main patch installation <|
-Extract this RAR file to any location.
-Backup your zdata_36.big, zdata_36.bh, zdata_38.big and zdata_38.bh by making copies of these files, then move them to a different folder. Preferrably, backup your WHOLE data folder (located at FIFA 10/data), if you have enough free disk space in your computer.
-Next, simply double-click on the mode you want to install, and wait for the command window to finish processing. And guess what! You're done
*(To have a more dynamic in-game experience, you may want to keep this folder open while playing the game. BEFORE or AFTER a match, you can switch from FIFA 10 to this folder, using Windows+Tab or Alt+Tab, and apply another mode. This way, you can play the next match with different lighting effects if you so wish)
|> Optional grass installation <|
-After installing any of the Editions above, backup zdata_42.big and zdata_42.bh
-Right-click 'Optional Grass Texture.7z', look for the 7zip or WinRar menu and select the option 'Extract Here'.
'
-Open the newly extracted folder, 'Optional Grass Texture', double-click 'Install Optional Grass Texture.bat' and wait for the command prompt screen to finish processing. And you're done.
*If you're not satisfied with the grass, simply restore the zdata_42.big and zdata_42.bh that you have backed up before this installation.
