*In PSvita the RCO's uses a cxml structure, with a header size of 0x50 and the magic identifyer '''RCOF'''
 
**RCOF header is 0x10 bytes bigger than any cxml header in PS3 (this means there are 2 new tables added for the new cxml variant used in vita rco's). And endianess changed because PSVita processor arquitecture
==CXML decompiler==
**Some of the extracted files (after cropped and zlib decompressed) are another variant of a cxml structure with identifyer '''RCSF'''
Experimental tool coded by flatz for documenting purposes, three versions of the tool was released publically in a IRC channel the same day (first and second versions had bugs that was identifyed and fixed)
**More info about this cxml variants in [http://www.psdevwiki.com/vita/index.php?title=RCO PSVita wiki]
 
The tool can extract the files contained inside a CXML container (CXML, QRCF, P3TF, RAFO, etc...), and generates an .xml that represents the original CXML structure
 
*Usage:
{{Keyboard|content=
'''C:\Portables\cxml decompiler v3 alpha>decompiler.exe coldboot.rafo coldboot.xml'''
}}
 
*Changelog
v1 alpha - Basic .cxml support
v2 alpha - Fixed a bug related with RAFO header (coldboot.raf support added)
v3 alpha - Fixed offset/length displacements in the function that locates float values (xml tag attributes related with x,y,z axis in 3D space now looks correct)
 
*CXML decompiler v3 alpha, download links: http://multiupload.biz/dnsipf0dkssz/cxml_decompiler_v3_alpha_MultiUpload.biz.7z.html
*CXML decompiler v3 alpha, source code:
