ROM cooking

I'm stuck

I'm trying to understand process of creating ROM, I've done thise steps:
1. Decompile *.NBH to *.NB files
a. Dutty's NBHTool http://forum.xda-developers.com/showthread.php?t=296311
b. NBHextract http://forum.xda-developers.com/showthread.php?t=289830
2. Deprotect ROM (Ervius ROM Deprotector http://forum.xda-developers.com/showpost.php?p=3102543&postcount=1)
3. OS.NB to OS.nb.payload (NBSplit.exe -kaiser Windows.nb) nb-> nb.payload+nb.extra
4. Extract imgfs (ImgfsFromNb.exe Windows.nb.payload imgfs.bin)
5. Create dump (imgfstodump imgfs.bin) imgfs.bin ->\dump\*.*

in the Dump folder many folders-files of DLLs, imageinfo.bin and imageinfo.txt for each of them.
Now how to decide where is OS and where is App's ?
what to \EXT of kitchen, what to \OEM, \ROM, \SYS ?

or I'm going wrong way ?
Pls "GooRoo of ROMs" help me :)

You only need ervius visual kitchen to do it all (has dutty's tool included). Open the erviuskitchen.exe and click on dump rom, navigate to the nbh file and the rest will be automatic (unless you are trying to decompile a protected (user-made) ROM)

Side note: this is not development related so I moved this to Q&A
