Hi there,

if the CTF Archiver doesn't work, use Patpat's newest version of "CTFtool GUI"

Its an excellent tool that makes theme creation and manipulation really convienient you can extract, pack, convert CTF's, dump RCO's etc.

Here's a tutorial on Cintro's which works on all Firmwares up to 5.50
