RCO
- 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
- Some of the extracted files (after cropped and zlib decompressed) are another variant of a cxml structure with identifyer RCSF. After a second extraction (with a cxml decompiler tool) the resulting file is a .xml containing only text strings (this double cxml method is used for .xml files that stores language translations)

- NOTE: The Child Element defination describe the Child Element and his Attributes where the Brother Element describe the Brother Element and his Attributes.
So the full order to read will be Child Element >>> Attributes, Brother Element >>> Attributes. The Root (so offset 0x00) of any SonyPlaystation Resource file always start's with a Child element to read.

FDICT
(Preset dictionary) If set, a DICT dictionary identifier is present immediately after the FLG byte. The dictionary is a sequence of bytes which are initially fed to the compressor without producing any compressed output. DICT is the Adler-32 checksum of this sequence of bytes (see the definition of ADLER32 below). The decompressor can use this identifier to determine which dictionary has been used by the compressor. |
FCHECK
value must be such that CMF and FLG, when viewed as a 16-bit unsigned integer stored in MSB order (CMF *256 + FLG), is a multiple of 31. |
About Data Compression:
Main Header
The header contains an identifier of the container (magic), his version, and allows to store the "absolute start offset" and "size" of 9 tables (or areas)
When a "not used table" is placed before a "used table"... the start offset of the "not used table" and his size (as zero) are stored in the main header to preserve his position in the structure. The "used table" that comes later starts in the same offset than the previously "not used table" (an intuitive way to think in this is imagining are overlapped because starts in the same position but only the one at the top is used)
- The container format is generic (used also by PS3 files like .RAF, .QRC and .P3T with some variations) so the usage of this tables can vary, in this example there is 1 "not used table":
- one of the "not used table" (at offset 0x18D0 with a size of 0) is placed before an used table (also at offset 0x18D0 but with a size of 0x34)
