No no that script was made for XP and it has been since altered so it can also work with VX, it's very popular on XP.
As for the code itself I'm not a scripter so I can't help you there sorry. But that script can also use the default battlers in place of the animated ones it comes with, it's all within the configuration section of the set of scripts it uses.
Within the Manual it's covered in this section:
Section 3 - Default Batter Style http://www.fileden.com/files/2008/10/3/212...ed_Battlers.pdf
To understand how the sheet works it's best to look at them within the demo and also view the image itselfI. This is if you're wanting to change from static images like the default battlers and use ones that will move and animate.
