 Posted: Wed Nov 21, 2007 1:10 am Post subject: GH3 PC Songs Decrypter |
 |
|
Hi everyone!
I've created a simple file decrypter for the GH3 PC version (the files inside DATA\MUSIC).
Just compile it in any visual studio (as a win32 console app)...
It accepts a fsb.xen file as input and decrypts it into FMOD FSB format (http://www.fmod.org/docs/tutorials/fsb.htm)
The fsb file contain mp3 files for the guitar, preview, rhythm and song.
None of the other files in the game is encrypted.
P.S.
The same code can also be easily modified to encrypt files ofcourse!
----------------------------------------------------------------
!!! CODE BEGINS BELOW !!!
----------------------------------------------------------------
| Code: |
#include "windows.h"
#include "stdio.h"
#include "sys\stat.h"
#define KEY_LEN 11
char SwapByteBits(unsigned char cInput)
{
unsigned char nResult=0;
for(int i=0; i<8; i++)
{
nResult = nResult << 1;
nResult |= (cInput & 1);
cInput = cInput >> 1;
}
return (nResult);
}
int main(int argc, char* argv[])
{
int nError = 0;
struct _stat32 fileStat;
unsigned int nBufferSize = 0;
FILE* inFile = NULL;
FILE* outFile = NULL;
unsigned char* pBuffer;
unsigned char* pInput;
unsigned int nLoopIdx = 0;
unsigned char cpKey[KEY_LEN] = "5atu6w4zaw";
printf ("GHIII FSB Decryptor v1.0 by Invo\n");
printf ("--------------------------------\n");
printf ("\n");
// Check params
if (argc != 3)
{
printf ("Usage: %s <Input> <Output>\n", argv[0]);
return (1);
}
// Get the file size
nError = _stat32(argv[1], &fileStat);
if (nError != 0)
{
printf ("Failed to get the input file size!\n");
return (1);
}
nBufferSize = fileStat.st_size;
// Allocate buffer
pBuffer = (unsigned char*)malloc(nBufferSize);
if (pBuffer == NULL)
{
printf ("Failed to allocate input buffer!\n");
return (1);
}
// Open and read the input
inFile = fopen(argv[1], "rb");
if (inFile == NULL)
{
printf ("Failed to open the input file!\n");
return (1);
}
printf ("Reading file (%d Bytes)... ", nBufferSize);
fread(pBuffer, 1, nBufferSize, inFile);
fclose(inFile);
printf ("Done!\n");
// Decrypt
printf ("Decrypting... ");
pInput = pBuffer;
for (int nLoopIdx=0; nLoopIdx<nBufferSize; nLoopIdx++)
{
*pInput = SwapByteBits(*pInput ^ cpKey[nLoopIdx % (KEY_LEN-1)]);
pInput++;
}
printf ("Done!\n");
// Open and write the output
outFile = fopen(argv[2], "wb");
if (outFile == NULL)
{
printf ("Failed to open the output file!\n");
return (1);
}
printf ("Writing file... ");
fwrite(pBuffer, 1, nBufferSize, outFile);
fclose (outFile);
printf ("Done!\n");
// The end...
return (0);
}

| provided this does in fact work, then all we need to do now is locate where the charts themselves are stored, and we can get modding on the pc version running |

| I can confirm that this indeed works. After compiling the posted code, I ran gh3extractor.exe <input> <output>. It outputs a .fsb file, which can be extracted using this. It extracts the 4 .mp3 files, the song preview, the guitar, bass/rhythm, and the rest of the song. |

| Altervista , Or at least I assume it requires registration. When I click on the link on your post it directs me to the homepage. http://it.altervista.org/ |

| Strange, it works fine when I click the link in Firefox but it doesn't work in Internet Explorer. I've uploaded it to my server, get it here: http://ar5enic.com/scorehero/fsbext.zip |

I am getting these errors with gcc:

main.cpp:45: error: invalid use of undefined type `struct _stat32'

I'm not sure what those errors mean, but I had deleted one of my other posts that mentioned you need to add the following include at the top of the code:

| The error should mean that _stat32 has not been defined and adding stdlib didn't fix it. |

| Ah, I just noticed you were trying to compile it with gcc...not sure how to compile it like that but I do know that it will compile in Visual Studio. |
