Ripping Questions

[Rhyme]

Hello.
I'm deeply sorry if this question has been already asked, but... anyway.

I'm trying to rip some things from the NDS game Code Geass Lelouch of the Rebellion. I managed to decompress .bin files from the game using a certain tool and now I've got NARC files. I can open those NARC files with NARCExplorer and extract what's inside. I'm pretty positive those are graphic files. So, inside those NARC files are four other files. These are their extensions:
.nanr
.ncbr
.ncer
.nclr

Now what do I do with them? From what I know one of them is a "map file" that can set the tiles right while viewing in a correct tile viewer, while another one is a pallete, another one for animation and another one is the image in question..
The question is, what tile viewer should I use to make something good out of those four files? I tried cristaltile2(i think that's it's name) but it doesn't seem to recognize .ncer files or I'm doing something wrong.

Please, can someone help me?

Oh, and exuse me if I'm missing something obvious here. I'm kinda new to this ripping thing.

Thanks in advance.

Try to use Tahaxan.. here.
Mind telling me how you decompressed the .bin files? it'd make my current project easier.
