HELP WITH GHIII FSB Decryptor

[skwaitne]

hi

i have an source code to compile a GHIII FSB Decryptor to extract songs from FSB files of guitar hero 3

but i dont know compile this

please, someone help me with this, im release the code to someone compile this or help me to compie:

#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);
}

I would also like to know how to compile this.
