Thanks to @gruce and all RevolutionTeam for the support.
It's simple the tool reads the String Resource DB of the game and Read the SPR , TGA and the NUI files too, Then it combine them togather as one piece and you can edit it , then save it.
The tool is easy to use , just put it in the decompiled game client so the tool can read the files . Note: The tool supports only UTF8 and ASCII as String resource database encoding .
