got it working.
I used Istools to edit the lsx made the folder names a bit nicer with it so id get CustomCompanions instead of CustomCompanions_(random code) i checked through brazucas mod and filled in the missing lines under moduleinfo

MenuLevelName Menuscreen_Cyseal
StartupLevelName CharacterCreation

and i also made a lsb with the same data using istools :P
