DS Nintendo NITRO-CHARACTER alternatives/crack

[New Nova]

Hello fellow humans.

Well, my IS-NITRO-EMULATOR is fully set up. But I have a small problem. SPRITES.
The official way is by using the Nintendo NITRO-CHARACTER software, but I need an online activation.
So 2 questions :
- Is there a way to crack the license of the software ?
- If not, are there other ways to create the following :
- Color Palette (.ncl files)
- Character (.ncg files)
- Screen (.nsc files)
- Cell (.nce files)
- MultiCell (.nmc files)
- Preview (.npv files)
- Scene (.nsn files)
for the Nintendo DS ?

Of course, my preferred way is to use the official tool, but I'm opened to suggestions.

Thanks in advance !

EDIT : I found the size of the response key :
1111111111111111111111111111111111111111
That's too much for bruteforce.
