Combined Effort LF2 - Questions (stage mode, Bat moves)

[Marioverraeter]

Thanks for your help, guys!
Okay, now I know what it is... well, I don't see the point of it, maybe it makes sense to lock the bonus characters, but why all base chars except of davis? o.O Whatever, that's the mod... hmm, is there any possibility for me to edit this stuff so that other characters are authorised to do the stage mode as well? I red somewhere that CE's code would be locked well and it's hard to do that's why I ask... and what exactly would I have to edit?
I know I'm asking for many things, I'm sorry, but help would really be appreciated! Thanks in advance, again. ^^

[off-topic]I'm German, Verraeter -> Verräter is the German word for traitor. This has nothing to do with my person, it's a hint on a namesake of mine in the RPG Gothic II. He is a traitor, and as my first registration to an online community was to one dedicated to the Gothic series, I thought of this to be a funny nickname. After that I never changed it in the internet whenever it was about a video game and every pal wonders what a kind of horrible freak I may be to call even myself a traitor. ^^[/off-topic]
