Common5.pac takes priority over sc_selchar and sc_selmap.
Either delete the Common5.pac or replace the sc_selchar and sc_selmap inside the common5.pac.
i'll try it, but it's weird, when i rip the original common5.pac from my PAL rom, it contains only some PokéTrainer files :/
EDIT: still doesn't work...
system is empty and in menu2 are sc_selcharacter_de.pac, sc_selcharacter2_de.pac and sc_selmap_de.pac.
when i'm using the pacs without _de, it freezes before the CSS is even showing up.
with _de it's loading from disc and is not replaced and freezes when selecting a new slot.
and common5.pac doesn't change something.
so why doesn't it replace the CSS and SSS?
