New cloop?

Hi,
I downloaded lnx-bbc 2.1 and tried to add some stuff as I did hundred of times 
in the past with the same procedure:
1) copied all the files from the cd in a local directory
2) extracted the compressed file system (singularity) and mounted it in a 
local dir
3) made an empty file (500 M ) with an ext2 filesystem
4) mounted the empty file and copied in all the files from the  extracted & 
mounted singularity
5) added some stuff from my old bbc (file manager, nmapfe, the old gui, ecc. 
ecc.) by mounting it with the same procedure.
6) umounted everythings
7) create_compressed_fs newfilesystem (500M)  16384 > singularity
8) mkisofs -b lnx.img -r -o ./lnx-bbc_cd.iso ./
It didn't work!!
I noticed that cloop.o is different, I tried the old one but It didn' t work ( 
as aspected..)
The problem is to mount the singularity fs during the boot.
Is cloop different and required a new version of "extract_compressed_fs" and " 
create_compressed_fs"? 

Thanks
