That will allow you to extract. I was working on this while trying to figure out some things on the original method to get the Galaxy 1.5 firmware working.
However, I am uncertain how to then recompile it back to a compatible system file. However I would assume that you could use the Yaffs tool to recompile though I am uncertain as I have not tried to recompile a system img.
I do agree with NU that it would probably be easier to file his method into compiling a flashable image though.
EDIT: I take that all back does not work with the new system from BH_Man... Sorry guys incorrect!
Using unyaffs works with the Galaxy images because that phone uses the YAFFS2 file system.
If you try to flash one of these with Odin to the Behold 2 it will not boot because it does not know how to use YAFFS2 - it doesn't have to - just RFS.
BH_Man's older ROMs used unyaffs because they were already packaged that way - but it had to be extracted so the phone could use the files.
