Image

The values marked in red are optional, the presence of the unknown specific for PS3 can be deduced based on the "rco version" in the rco header, only exists in PS3 RCO's (PSP doesnt uses it). See rcomage talk page. The presence of the other optional value file_uncompressed_size can be deduced by reading the entry itself

The file_compression feature adds a compression layer over the file format (pointless for image formats that are nativelly compressed like GIM or JPG)

Offset	Length	Name	Example	Notes
0x00	0x02	file_format		0x0=PNG 0x1=JPEG 0x2=TIFF 0x3=GIF 0x4=BMP 0x5=GIM
0x02	0x02	file_compression		0x0=NONE 0x1=ZLIB 0x2=RLZ
0x04	0x04	file_size		either compressed or uncompressed, this is the final size of the file stored inside the rco
0x08	0x04	file_offset
0x0C	0x04	unknown		Most PS3 RCOs have this extra value - probably something to do with planes/frames?? usually 0x1
0x10	0x04	file_uncompressed_size		Optional. Doesn't exist if file_compression = NONE, for PSP is located 4 bytes before because the previous value doesn't exists

• unknown
  • RCO files version 0x93 included in some PS3 pre-retail firmwares (such DECR 082.006) doesnt have this value. But rcomage expects it to be there and when trying to extract the RCo contents it returns an error, loses the TOC track, and then does a "jump" of 4 bytes to locate the TOC track again and continue reading, The problem doesnt seems to be critical, the extraction is fine (the rebuilding not). This is an example of the error on system_plugin_bg.rco DECR 082.006

Warning: [entry (0xf4)] Unexpected value 0x20a4 for PS3 image - expected 0x1.
Warning: [entry (0xcc)] Entry boundaries not aligned (going forward -4 bytes)
