Notes and Comments

  • Archives may be compressesed with custom compression algorithm. Implementation from FUEL toolkit may be found here.
  • Archives may use custom CRC32 hashing function.
  • File format is shared with many "Asobo Studio" games.
  • Extensions may be described as follows: DPS = "Data PlayStation", DPC = "Data PC", DXB = "Data Xbox", DPP = "Data PSP", DRV = "Data Wii", D36 = "Data Xbox 360".
  • In "Garfield 2" PC game there are also *.NPC and *.LAYOUT files which contains filenames and database entries for *.DPC archives.
    In "FUEL" PC game there are some *.IWR files which also contains some database entries.
    In Monopoly Plus PC game there are NPC and LPC files with database entries.
  • In "Racket Sports Party" Wii game there is string "x:\Datas\$$$IncrediBuilder$$$\X##DATAS#_MASTER#RACKET_DATAS\KIT-WII\" in every *.DRV archive
    which may suggest that archives were build with IncrediBuild software.
  • Archive version numbering suggests that Asobo Engine has been rewritten in 2006.
