RCO Structure

The container structure can be represented as an XML (see RCOXML), with rcomage is posible to generate this XML when extracting, and for rebuilding the rco using the XML as a layout

info/main/xml table

This area works as an index of all the .rco contents, when the area is compressed there are 12 bytes at the beginning with info about this compression, after it starts the info composed by entries that follows a hierarchy of parent/children/brother, every entry defines an element with its attributes. All this info can be represented as an xml file (this is what rcomage names an RCOXML)

When the table is compressed at beginning there are 3 values related with the compression (otherway if the table is not compressed this 3 values doesnt exists)

Offset Length Name Example Notes
0x00 0x04 lenPacked Packed size of all the table sections
0x04 0x04 lenUnpacked Unpacked size of all the table sections
0x08 0x04 lenLongestText length of the longest language's text data (unpacked)

And then it starts with the entries, every entry has an area at beginning that is common, in it is specifyed the entry_type, the values that comes after this area are dependant of the entry_type

Offset Length Name Example Notes
0x00 0x01 hierarchy_depth ? main table uses 0x01, may be used as a current entry depth value
0x01 0x01 entry_type *0x1=MainTree
*0x2=ScriptTree
*0x3=TextTree
*0x4=ImageTree
*0x5=ModelTree
*0x6=SoundTree
*0x7=FontTree
*0x8=ObjectTree
*0x9=AnimTree
0x02 0x02 unknown Always seems to be 0x0000
0x04 0x04 entry_label_offset Offset to the label (relative to the label table). 0xFFFFFFFF means the label doesn't exist for this entry
0x08 0x04 entry_header_size sizeof(RCOEntry) = 0x28 [ only used for entries with extra info (ie not "main" entries) ]
0x0C 0x04 entry_size main tables (main/img etc) uses 0x28 here, or is this the length of current entry (not including subentries)?
0x10 0x04 children_number
0x14 0x04 next_entry_offset
0x18 0x04 previous_entry_offset
0x1C 0x04 parent_offset
0x20 0x04 unknown Always seems to be 0x00000000
0x24 0x04 unknown Always seems to be 0x00000000

After the area common for all entries it starts the info specific for the entry_type, in wiki this has been separated in different pages...
