For Riivo it's in your Common5.pac under sc_selcharacter. Specifically it's MiscData(70).
Your common5.pac goes in your system file.
If you're using Gecko you'll find it still inside sc_selcharacter MiscData(70), however your sc_selcharacter file will go inside the Menu2 folder.
Okay. And can you also tell me the directory on a SD card?
Thanks dude!
