Interesting facts
The AFS archive (IMAGE.AFS) of the PS2 version, once extracted and sorted, has the same files as those present in the folder Image of the PC version. These files seem to be mostly compatible although the content of some of them does not load, especially some images. The AFS archive also contains .irx files (Dynamic Libraries for PS2) and an ioprp280.img which are not part of the PC version. Also, the PS2 files contain 5 audio files not present in the PC versions.
