Deer Hunter Tournament....

[aluigi]

well done bacter.
I have updated my dh2005 script adding a simple scanner for finding the right key of the 4 available (2005, demo, custom and tournament).

so I guess that the only problem remains in those shaders.spk archives of DHT but I don't have one of them at the moment so I can't verify them

Tip: Try to check the Size and the CRC32 of the Entries:
IF STOREDSIZE=0 AND CRC32=0 ---> good entry, file with zero size
IF STOREDSIZE=0 AND CRC32<>0 ---> BAD ENTRY

Example bad entries from DHT:
(storedsize#flag#originalsize#crc32#unknown#filename)
Data.Shaders.Win32.v1.spk:
00000000#08#00000000#ED030B6F#16CA0B40#fxdata\_def_glossiness.png
00000000#08#00000000#81B267A3#16CA0B40#fxdata\_def_heatgradient.png
00000000#08#00000000#618B2EA4#16CA0B40#fxdata\_def_noise.png

Data.Shaders.Win32.v2.spk:
00000000#08#00000000#ED030B6F#16B697E0#fxdata\_def_glossiness.png
00000000#08#00000000#81B267A3#16C1DC60#fxdata\_def_heatgradient.png

O.K. Here's every important information I collected about the .SPK files:
There are 3 different versions of SPK files, so first always check the Header's version number! (They use different Header size, and different Entry sizes!!!)

If 1 or 2, then no problem, but the 3 contains some more trick, the decoding needs a MASTER_KEY, which is game-dependant. These MASTER_KEYS are derived from some passwords:

Deer Hunter Tournament: (I didn't find demo version of the game, so this is for the full version)
MASTER_KEY=0x48C20726 comes from this: "winmm.lib!ddraw.lib"

Deer Hunter 2005 FULL:
MASTER_KEY=0x32E105A4 comes from this: "dh2005.exe;d3d.dll"

Deer Hunter 2005 DEMO:
MASTER_KEY=0x3CB80690 comes from this: "d3dx.lib;ddraw.dll"

DeerHunter 2005 custom level:
MASTER_KEY=0x18D9042F comes from this: "dh2005custom"

Trophy Hunter 2003 + Deer Hunter 2004 use the v1 or v2 format, so they don't need password or MASTER_KEY

Code: Select all

The .SPK file starts with this header:

Type DeerHuntTour_SPK_HeaderType = Packed Record // 12 or 13 bytes!
       APK_ID : Array[0..2] Of char; // 'APK'
       VersionByte : byte; // (1,2 or 3)
       DirStartPos : dword; // points to the end of the file
       DirOrigSize : dword; // the original, unpacked size of the directory data
       // ----------------------------
       // This, last byte is only if the VersionByte = 3 !!!!!
       MoreCryptFlag : boolean; // 1 byte! Indicates more encryption!
     End;

The file information data is compressed (with zlib) and encrypted.
So first we need do decrypt:
If version=1 or 2 then:
  DeerHunter_Encrypt(Buffer,Hdr.DirStartPos * Hdr.DirOrigSize,FALSE);

If version=3 then:
  you can generate the MASTER_KEY, from the appropriate password:
  MASTER_KEY := DeerHunter_GenerateMasterKey('... place of the password...');
  and then:
  DeerHunter_Encrypt(Buffer,MASTER_KEY Xor Hdr.DirStartPos Xor Hdr.DirOrigSize,Hdr.MoreCryptFlagByte);

If everything is OK, the decoded buffer now contains zlib compressed data.
Unpack it. The unpacked data size must be equal to the value of Hdr.DirOrigSize

Now we can process the Entries (repeat until the end of the buffer):

Type DeerHuntTour_SPK_EntryType = Packed Record
       Name : Array Of char;  // The filename, with a terminating zero character
       StartPos  : dword;     // start of the file data
       StoredSize  : dword;   // the stored size (the compressed size, if compression used, otherwise the original size)
       FlagsByte : byte;      // 00 = stored
                              // 01 = encrypted
                              // 02 = zlib_compressed
                              // 03 = zlib_compressed+encrypted
       OriginalSize  : dword; // the original size
       CRC32  : dword;        // the crc32 value of the original file
       //-----------------------------
       // This, last dword is only if the VersionByte = 2 OR 3 !!!!!
       unknown  : dword;      // absolutely unknown value
     End;

If the file data is encypted ( (Entry.FlagsByte AND 1) = 1) then use the same decryption method as above:
If version=1 or 2 then:
  DeerHunter_Encrypt(DataBuffer,(Entry.OriginalSize * Entry.StartPos) Xor Entry.CRC32  );

If version=3 then:
  // we generated the MASTER_KEY, so we can use it again:
  DeerHunter_Encrypt(DataBuffer,MASTERKEY Xor Entry.OriginalSize Xor Entry.StartPos Xor Entry.CRC32,Header.MoreCryptFlagByte);

still a no go on packing the resources
Data/Animals which would be Data.009
Data/Globals which would be Data.010
DataInterface which would be Data.011
Data/Weapons which would be Data.012

Devrim wont share his program and will only let us have it for 50.00 usd he said because of all the new things that will be in dh2004 and dh2005 and his works he saud he used luigi's script for unpacking and denniz's script for packin ive tried everything and nothin happens

DHT is a whole new story we will have to find a s3d imorter/exporter for new models

[Unforgiven]

it all works 100% i figured it out

would ya rather have forum name or real name in credits ?

[bacter]

I updated my program. Little cosmetic changes: If you open or extract a SPK file, the list jumps to the correct game version.

Unforgiven:
#1: What was the solution?
#2: You can mention my forum name (bacter) in your credits if you want.

[Unforgiven]

it was simple actually

i was tryin to pack the edited files within the game directory which would pack but wouldnt load up in game.
so them i figured ive tried everything there is so why not try this ( this was the solution)

Right clicked on Desktop created new folder, renamed the folder Game
then inside the game folder i created a data folder

put all of our work inside of it and packed it with ur deer hunter util and it works flawlessy on all games

[bacter]

aluigi!
Now I solved the script problem with the "Data.Shaders.Win32.v1.spk" and "Data.Shaders.Win32.v2.spk"!
Your script, line 31-32, when you allocate some memory for the dir table decompression:
set OUT_INFO_SIZE long INFO_SIZE
math OUT_INFO_SIZE *= 8 # more than enough

file1: 26,656*8 = 213,248 -> but we need: 228,780
file2: 27,222*8 = 217,776 -> but we need: 228,780

So, we need some more memory, for example:
math OUT_INFO_SIZE *= 10
or, the simple and elegant way (because the header contains the uncompressed size):
set OUT_INFO_SIZE long CRYPT_INIT

corrected, thanx bacter :)

[deve]

the tool works but have somebugs, like when you pack dh04 files or sometimes it just doesnt pack says only "error:("

anyway I have a question about , dh05 when the data.001 is packed and I make new changes and pack it us data.002 the game reads only the data.001 and not other data.00x , how can we fix this ?
