Sorry for making so many requests, but is there any way to extract and repack these .DAT files that a PS1 game uses called Crash Bash? I really want to see this game get modded in some form or another!

.DAT file:

105 MB decompressed

I see no headers or information or known file formats.
At the beginning there is something that "looks" like an header but it contains nothing to be used.
This script tests the sort-of header at the beginning and show that there is nothing:

Code:

debug 1 # show all the fields

goto 0xa
get FILES short
goto 0x20
for i = 0 < FILES
    get DUMMY long
    get DUMMY long
    getdstring DUMMY 0x1c
next i

I'm not sure why the data is that way. I guess this is one game that cannot be modified.

I can see that there is some pixel data for the loading/menu screens ("Sony Computer Entertainment Europe Presents", etc) in the file, in 1555 format with a width of 512 pixels. Unfortunately that seems to be all I can find, not textures or anything. As aluigi says it doesn't really seem to be extractable anyway.

Maybe there is an index file containing the information for extracting the files.

I have another request; It's for a different game, but it's the same series. It is a game called Crash Bandicoot: The Wrath of Cortex. I found this .DAT file that apparently contains the character models.
Not sure if this can be extracted/reimported, but here it is if you want to give it a go;
