Error translation

In various places Vita may display errors translated into their string representation. The code below also does this, provided you feed it with a copy of os0:kd/error_table.bin. 

#include <stdlib.h>
#include <stdio.h>

#ifdef _MSC_VER
#define snprintf _snprintf
#endif

int read_error_table(const char *path, void *buf)
{
  unsigned int v6; // r1@6
  unsigned int v7; // r1@10

  FILE *f = fopen(path, "rb");
  if ( f )
  {
    if ( fread(buf, 1, 8, f) == 8 )
    {
      v6 = *((short *)buf + 2);
      if ( v6 <= 0x20 )
      {
        if ( fread(*((int *)buf + 2), 1, 8 * v6, f) == 8 * v6
          && fread((char *)buf + 12, 1, 4, f) == 4 )
        {
          v7 = *((short *)buf + 7);
          if ( v7 <= 0x36B0 )
          {

              return 0;
            }
