Almost everything is done but small towns and bhujerba

Installation.
1 - Backup the "FFXII_TZA.vbf" file first. (Or simply backup the original music folder)
2 - Open up the VBF BRWOSER tool (https://www.nexusmods.com/finalfantasy12/mods/3)
3 - Open the "FFXII_TZA.vbf" file with the tool
4 - Move to the folder (on the right side) ps2data>sound>music>magi_data>win (Don't use inject because i'm stupid and forgot to setup the folder structure)
5 - drag and drop the modified sound file here and wait till the tool say "done".
6 - This is very obvious but install in the right order (main file, update 1>2>3>
7 - In game, select original soundtrack in the option. Orchestrated is keept intact, note that i had to replace the Original CD music for some of the tracks.

Uninstallation
See "1", 


Known issues.
Outside of the common loop that may be wrong in some tracks, and a volume too low for some. The game love the star w.. imperial song and there's a lot of duplicate and i may have replaced the wrong one in some cases, or i may have missed one.
I also had the replace the CD soundtrack (third option) for some of the tracks, for reason i don't know i had to replace it otherwise the music was not working.
The game also love to reuse some part of field music during some event, i can't do anything about that.
