Somebody can help me to extract this compressed file format, please?

Here's the BMS script to decompress the PAC file:

pac_decompress.bms

Code:

comtype lzss0

get UNK long # Always 0x01
get SIZE long
savepos CURRPOS
get ZSIZE asize
math ZSIZE - CURRPOS
get NAME basename
string NAME   .dec
clog NAME CURRPOS ZSIZE SIZE

And here's the script to extract the files from the resulting dec files

dec_extract.bms

Code:

get FILES long
padding 16
xmath OFFSET "FILES * 0x20   0x10"
for i = 0 < FILES
   getDstring NAME 16
   get SIZE long
   padding 16
   log NAME OFFSET SIZE
   math OFFSET   SIZE
next i
