need help with the Script "Success"

Please, could anyone explain to me how to use the script?
This one: http://projectdxxx.me/script/index/id/0edba61f78712fe0777140aaa7e564d4
I'm trying to make it work but since I don't know Japanese, I really can't figure out how...
Thank you so much

To use it u need to follow these steps:
1: Download it
2. Extract the folders "Effect,Image,and Sound" to the songs "Resource" folder (Ex: C:/KHC/PPD/Projects/SadisticsMusicFactory/Resource) and override folders.
3: Copy the success.fmsl to the difficulty scripts (Ex: C:/KHC/PPD/Projects/SadisticsMusicFactory/Hard_Script and a copy to the C:\KHC\PPD\Projects\(Difficulty)_Scripts dir.
4. For first time, copy Success.xml to the preset_parameters folder (C:/KHC/PPD/preset_parameters).
5: Open PPDEditor script manager and edit the value string to the amoung thts rainbow colored. Default its value is zero.

Hope the explanation helped.
