Here's the script to extract the PAC.BIN
The executable must be in the same directory as PAC.BIN file

Code:

open FDSE SLPS_256.70
open FDSE PAC.BIN 1

math TOC = 0xB7790
goto TOC

for i = 0
   get HASH  long
   get HASH2 long
   if HASH == 0 || HASH2 == long
      break
   endif
   get OFFSET long
   math OFFSET * 0x800
   
   get SIZE long
   get UNK long
   get ZERO long
   
   string NAME p "d." i
   log NAME OFFSET SIZE 1
next i

And here's the script to decompress/extract the files inside the .img/.dat/.upa files
Note: Not all dat files are archive files. The one after the upa files is stereo Sony ADPCM audio file.

Code:

comtype lzss0

getDstring MAGIC 4

if MAGIC == "UPAC"
   get UNK long
   get START_OFF long
   get FILES long
   for i = 0 < FILES
      savepos TMP
      get ZSIZE long
      get ZSIZE2 long
      get ID long
      get SIZE long
      math ZSIZE2 - 8
      savepos TMP2
      string NAME p "d." i
      clog NAME TMP2 ZSIZE2 SIZE
      math TMP   ZSIZE
      goto TMP
   next i
else
   goto 0
   for i = 0
      get OFFSET long
      get SIZE long
      if SIZE == OFFSET
         break
      endif
      get UNK long
      log MEMORY_FILE OFFSET 8
      getDstring MAGIC 4 MEMORY_FILE
      string NAME p "d." i
      if MAGIC == "LZS"
         math ZSIZE = SIZE
         math ZSIZE - 8
         get SIZE long MEMORY_FILE
         math OFFSET   8
         clog NAME OFFSET ZSIZE SIZE
      else
         log NAME OFFSET SIZE
      endif
   next i
endif
