The first game id like a script for is for Cabela's African Safari's .arc files.
For those who dont have the game ive uploaded one of the arc files so you can try and crack it.
http://rs348.rapidshare.com/files/133640664/data2.rar
just extract the rar file and the .zip file and thats were you'll find the arc files. I put it in a rar file to compress the size and to make it a faster download.
The other game game I want to view the files of is DreamStripper which uses .cbn archive files.
Again ive uploaded a archive file from the game for those who dont have it in order to try and open it.Just a warning it is an adult game so that the .cbn archive might have some naughty content in it. Like textures for some of the models.

I don't think people would like to download 170M unknown file to see what's there!? Actually I had downloaded it and that arc file is zlib packed. But there is not index table inside the arc, it means there should be another index file to tell what files, offset, length etc inside the arc.
The CBN archive is easy. And this game use granny engine as well!
Code: Select all
dword unknown //Header??
dword numFiles
struct IndexTable {
dword ofsFile
dword ofsLength
dword Len
char[Len] FileName
}
<data>
I don't have MultiEX atm, so I don't know if the script works or not
Code: Select all
# DreamStripper CDN Mexscript
# by Fatduck edited 04Sep08

Set START Long 4;
GoTo START 0;
Get FCOUNT Long 0;
For T = 1 To FCOUNT;
Get OFSDATA Long 0;
Get OFSSIZE Long 0;
Get DSTGLEN Long 0;
GetDString FNAME DSTGLEN 0;
Log FNAME OFSDATA OFSSIZE 0 0;
Next T;

Damn it said multiex could not process it. But thank you for trying. Could someone try and and edit it to make it work? Also what is the top code used for? I know the bottom is the bms script but what am I supposed to do with the top one?

I had another look of Cabela's African Safari's ARC today. And I think I figure out the format now!
The archive is divided in 0x800 a chunk. And the header is located at the last chunk 0x0A77E800
Code: Select all
Offset 0 1 2 3 4 5 6 7 8 9 A B C D E F
0A77E800 41 52 43 00 00 01 00 00 F6 4E 01 00 D4 C2 01 00 ARC.....譸..堎..
0A77E810 9A 34 00 00 B0 05 00 00 00 00 00 00 00 00 00 00 ?..?..........
And the format of the header is:
Code: Select all
char[4] Magic //"ARC\0"
dword Ver??
dword ofsChunkIndex //this is the indices table, real offset need * 0x800
dword UnCompressedSize
dword CompressedSize
dword numRes
The indices table is zlib compressed, after uncompressed it, the format will be:
Code: Select all
struct Resurce {
char[4] Magic //"ARCH"
dword ofsChunkStart
dword ofsChunkSize
dword UnCompressedSize
dword CompressedSize
dword CompressionFlag //-1 = compressed, 0 = raw data
dword nLen
char[nLen] ResName
}

Darn it fatduck! I just discovered you figured it out today but I already uninstalled the African safari game this week so I could have room in my hard drive to install spore and age of conan!

For 010 Editor
Code: Select all
FSeek(FileSize() - 0x800);
char Magic[4]; //"ARC\0"
uint version;
uint ofsChunkIndex<format=hex>; //this is the indices table, real offset need * 0x800
uint UnCompressedSize;
uint CompressedSize;
uint numRes;
FSeek(ofsChunkIndex * 0x800);
uchar indicesTable[CompressedSize];
after uncompressed the indices table
Code: Select all
typedef struct {
char Magic[4]; //"ARCH"
uint ofsChunkStart<format=hex>; // real offset need * 0x800
uint ofsChunkSize; // real size need * 0x800
uint UnCompressedSize;
uint CompressedSize;
int CompressionFlag; //-1 = compressed, 0 = raw data
uint nLen;
char ResName[nLen];
} FILES;
while( !FEof() )
{
FILES file;
}
