Stage Icons - In which file?

[Teschi]

Hey guys,
I just wanted to ask,where the data in stages is,that says,which SSS icon they have.I DON'T want to edit or replace.
Example:
I already edited the Pictochat DS-Symbol to MH3 Symbol,caus on Pictochat is now Jhen Mohrans Stage.
Now i want to put a second Mh3 Stage over Final Destination,but dont wanna edit the "Brawl" Symbol,because Battlefield uses the same icon.
You know what i mean?
Now i want to switch,that Final Destination have the Mh3-icon,that i replaced for the Pictochat/NDS icon.
I dont use Riivolution or other things,i'm editing the iso(PAL)
