That IDX doesn't contain information about the PKG data files you provided.
For example the first packfile is 9 inside the IDX.
Anyway I see no problems in that script, the OFFSET, ZSIZE and SIZE fields seem correct.

Ok it helps.

In my opinion the KFM files are encrypted/obfuscated.
I have checked it and from offset 0x38FB6D of package 323 there is no zlib data, so more than half archive is probbaly encrypted.

I leave here a script that does the same things of the one you posted but is lot shorter, just in case someone wants to edit it:

Code:

math OFFSET = 0x124
open FDSE pkg.idx
get files asize
math files - OFFSET
math files / 0x250
goto OFFSET
math MYPACKFILE = -1
for i = 0 < files
    get FILENUM long
    get OFFSET long
    get unk02 long
    get ZSIZE long
    getdstring DUMMY 40
    get SIZE long
    getdstring file 0x104
    getdstring NAME 0x108
    string NAME   file
    get packfile long
    get unk15 long

    if PACKFILE != MYPACKFILE
        string PCK p= "pkgd.pkg" PACKFILE
        open FDSE PCK 1
        math MYPACKFILE = PACKFILE
    endif
    if ZSIZE != SIZE
        clog NAME OFFSET ZSIZE SIZE 1
    else
        log NAME OFFSET ZSIZE 1
    endif
next i
