You can find and post info about UBCD Creator at:
Ultimate Boot CD Forum Index -> UBCD V5 Discussion -> UBCD Creator
Currently only the first release is out (beta1), which can only remaster the UBCD iso. If you have any feature request, post it there.
For UBCD v4.11 you can find a list at: http://www.ultimatebootcd.com/
For UBCD v5.00 you can find a list at: http://ultimatebootcd.com/index50.html
But I suggest that you wait until UBCD v.5.00 is out.
You can download the current beta to see how it looks at: http://www.ultimatebootcd.com/forums/viewtopic.php?t=1550
You can find the information about also in the config files (/menus/*.cfg
in the ubcd411.iso or /ubcd/menus/*.cfg
for ubcd500.iso), which give also the links to the files that you should delete).
