Initial D Special Stage .PAC 3D Files

Extracted from an .AFS Archive, this is the standard model type for this game for cars/courses (.PAC) and I know it's been covered before with many other games but i've had no luck using the same tools on these. Can someone give me a hand? I'm sure this will be pretty quick compared to other things.
Sample course file (full size 2MB, not a large download, smallest one):

And a sample car file (1MB):

Thanks!

This QuickBMS script unpacks content from the PAC files:
Code: Select all
idstring "PAC\0"
get FILES long
get DUMMY long
get SSIZE long
getdstring FOLDERNAME 16
for i = 0 < FILES
getdstring NAME 16
get OFFSET long
get SIZE long
get FOLDER long
get DUMMY long
savepos TMP
goto OFFSET
getdstring SIGN 3
if SIGN == "GIM"
string NAME p= "%s.%s" NAME SIGN
elif SIGN == "CMD"
string NAME p= "%s.%s" NAME SIGN
else
string NAME += ".DAT"
endif
goto TMP
log NAME OFFSET SIZE
next i
CMD files are models, and GIM files are textures. I can't find a program that can read them though.

the cmd looks like a modified version of folklore's model format.

Cheers for both of your replies guys, didn't expect this to take off so quickly
That script functions perfectly on the car Models but only creates .dats and .gims on the Course. All the dats feature the same header here: (It also produces correct file names IE lodxx and named objects, which is nice I guess)
With a few pointers to a program which could read folklore's model format (to be used on these if the modifications aren't too extensive), I could get the car models and textures working just fine.
Here's a sample .dat LOD file just incase you can identify the file's header. Thanks for your input!

EDIT: In addition, Noesis won't read the produced .gim files for either car or course model. Hmm.

The .dat file looks like it might be encrypted - "SMD" could be a garbled version of "CMD" and "KINA_NI˙T254_000" looks like it might be some kind of a model or material name.

So you can open the car models and textures? And how extract the .afs?
