 The game files in PS2 Oni are structured similarly to PC Oni, but with some notable differences.
 * The disc contains duplicate copies of a strangely-small persist.dat, at the paths /PERSIST.DAT and /2. (Note that Oni (PS2) saves its progress to the memory card like every other game, so these files are vestigial.)
-* Renamed files. It appears that PS2 file naming is subject to the 8+3 limit seen in DOS. In order to work around this for the longer names used in [[IGMD]], the files are simply named with consecutive numbers on disc, and the real names are given in INDEX.DIR files in the same directory.
+* Renamed files. It appears that PS2 file naming is subject to the 8+3 limit seen in DOS. In order to work around this for the longer names used in [[IGMD]], the files are simply named with consecutive numbers on disc, and the real names are given in INDEX.DIR files in the same directory. Here is the overall structure of the directory with decoded names and commentary:
-* The folder /1/ is GameDataFolder. Inside of this, the usual .dat files are present, but the .raw and .sep files have been moved to the subdirectories 20/ and 21/. Additional .pal ("palette") files are also stored in a subdirectory, 19/. A new .raw file for the Main Menu loading screen, LOADING.RAW, is at root level of the disc.
+** 1/ - GameDataFolder/
-* It appears that all sound data has been broken out into a new set of .dat/.raw/.sep files in /SOUNDS/.
+*** 1/ - IGMD/, with the same unused level scripts found in [[OBD:Localization/German|German Mac Oni]]
-* The files /1/2 and /1/18 are the original .bik movies from PC Oni, taking up space on the CD-ROM for no reason. This is in addition to the PSS (PlayStation 2 video format) versions of intro and outro at root level, which take up 33% of the total space on the volume!
+*** 2 - intro.bik (unused by game)
-* In the IGMD folder (/1/1/), the same unused level scripts are found as in [[OBD:Localization/German|German Oni]].
+*** 3/…17/ - the game's .dat files, but the corresponding .raw and .sep files have been moved to the subdirectories 20/ and 21/
+*** 18 - outro.bik (unused by game)
+*** 19/ - .pal ("palette") files
+*** 20/ - contains the .raw files which go along with the .dat files in this directory
+*** 21/ - contains the .sep files which go along with the .dat files in this directory
+** 2 - persist.dat (PC version, unused)
+** 3 - Preferences (another vestigial file, pointing to a GameDataFolder on someone's hard drive)
+** ICONS/ - contains one icon, the Oni icon, apparently in a PS2 format
+** INTRO1.PSS and INTRO2.PSS, discussed under "Visual differences"
+** LOADING.RAW - a new data file for the Main Menu loading screen added to PS2 Oni
+** MODULES/ - standard libraries for a PS2 game
+** OUTRO.PSS - the outro animation and credits, discussed under "Visual differences"
+** PERSIST.DAT (PC version, unused)
+** SLUS_200.64 - the game binary
+** SOUNDS/ - it appears that all sound data has been broken out into a new set of .dat/.raw/.sep files
+** SYSTEM.CNF - standard boot information for a PS2 game
+* It's surprising to note that the original .bik movies from PC Oni are taking up space on the CD-ROM considering the game cannot play them and the PSS (PlayStation 2 video format) versions of these movies are already taking up 33% of the total space on the volume. It would seem like the GDF is a straight copy-and-paste from the PC version, except that it's not because all the game data was repacked and restructured.
