Model
Uses the same values than Images with a couple of differences, the table is repeated here for comparison purposes
The presence of the unknown (specific for PS3) is completlly speculative because never has been found a GMO file used on PS3 official firmware, is not even known if PS3 firmware has some function able to manage GMO files, it works
| Offset | Length | Name | Example | Notes |
|---|---|---|---|---|
| 0x00 | 0x02 | file_format | 0x0=GMO | |
| 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 | Offset of data relative to the beginning of the image data section | |
| 0x0C | 0x04 | unknown | PS3 RCOs seem to 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 |
