That's offset 0D (You have it set to F2 there) which controls character count. You'd be able to use a calculator or something find out what number you need (Mostly just to convert from Decimal to Hex)
As for cosmetics, inconsistent how?
Despite setting the IDs correctly in the sc_selcharacter.pac and info.pac, the marks and names don't match with most of the characters I added. Also, the character portraits (loaded from char_bust_tex in the BrawlEx folder) for the EX fighters don't show up either...
