Fate/Extra pak archives

[finale00]

I extracted the cpk archive using cpk_unpack and among some compressed archives I found some pak archives which were uncompressed (a lot of them had "RIFF WAVE" near the top)

The format is looks simple and should take some people only a couple minutes (just a table at the top followed by the data afterwards) but ya here are some samples:

[WRS]

Code: Select all

get FILES short
get UNKNOWN short

for f = 0 < FILES
  get TMP long
  putarray 0 f TMP
next f

padding 16

for f = 0 < FILES
  getdstring NAME 64
  savepos POS
  getarray SIZE 0 f

  log NAME POS SIZE

  math POS += SIZE
  goto POS
next f

Now I know how to use arrays lol

this bms script will decompress your sample

Code: Select all

# script for QuickBMS http://aluigi.altervista.org/quickbms.htm

comtype lzss0
idstring "IECP"
get ZSIZE asize
get SIZE long
savepos OFFSET
math ZSIZE - OFFSET
get NAME basename
string NAME + _decmp.cmp
clog NAME OFFSET ZSIZE SIZE

Thanks a lot AceWell! How to edit string "bla-bla-bla" for all files compression?

cmp_compressor.bms:

Code: Select all

# script for QuickBMS http://aluigi.altervista.org/quickbms.htm

comtype lzss0
idstring "bla-bla-bla"
get ZSIZE asize
get SIZE long
savepos OFFSET
math ZSIZE - OFFSET
get NAME basename
string NAME + _decmp.cmp
clog NAME OFFSET ZSIZE SIZE

[Acewell]

if you're sure they all use the same compression you could just replace that line with one of these

Code: Select all

get blablabla long

or

Code: Select all

goto 0x4

or

Code: Select all

getdstring blablabla 4

i hope i'm understanding what you mean

[makcar]

That's right?

[Acewell]

That's right?

i guess so, modding is not my area, but it looks okay.
