its not that hard to create a signature the really problem is finding the right signature on windows.

[Bugsy]

Yeah, I know, but thought a little wizard would be a cool way to simplify it.

And yes, it's annoying finding them, if you get lucky there is a string within the function which you can first identify in the linux decompile (or these days regamedll) and then find that same string in the windows code to find the correct function.

[Bugsy]

Here's an example:

You want to hook Host_ValidSave()

Look at the linux decompile or regamedll

int Host_ValidSave(void)
{
    if (cmd_source != src_command)
        return 0;

    if (!g_psv.active)
    {
        Con_Printf("Not playing a local game.\n");
        return 0;
    }
    if (g_psvs.maxclients != 1)
    {
        Con_Printf("Can't save multiplayer games.\n");
        return 0;
    }
    if (g_pcls.state != ca_active || g_pcls.signon != 2)
    {
        Con_Printf("Can't save during transition.\n");
        return 0;
    }
    if (g_pcl.intermission)
    {
        Con_Printf("Can't save in intermission.\n");
        return 0;
    }
    if (g_psvs.clients->active && g_psvs.clients->edict->v.health <= 0.0)
    {
        Con_Printf("Can't savegame with a dead player\n");
        return 0;
    }
    return 1;
}

Search for those same strings in the Windows decompile, and you have your function, sub_1D479C0().

signed int __cdecl sub_1D479C0()
{
  signed int result; // eax@3

  if ( dword_269A21C != 1 )
    return 0;
  if ( !dword_21D4A00 )
  {
    sub_1D2C030("Not playing a local game.\n");
    return 0;
  }
  if ( *(_DWORD *)dword_21D3E88 != 1 )
  {
    sub_1D2C030("Can't save multiplayer games.\n");
    return 0;
  }
  if ( dword_26EBA80 != 5 || *(_DWORD *)dword_26EEF9C != 2 )
  {
    sub_1D2C030("Can't save during transition.\n");
    return 0;
  }
  if ( dword_271D200 )
  {
    sub_1D2C030("Can't save in intermission.\n");
    result = 0;
  }
  else
  {
    if ( *(_DWORD *)dword_21D3E84 && *(float *)(*(_DWORD *)(dword_21D3E84 + 19356) + 480) <= 0.0 )
    {
      sub_1D2C030("Can't savegame with a dead player\n");
      result = 0;
    }
    else
    {
      result = 1;
    }
  }
  return result;
}

Thanks bugsy for the explanation it was very helpful.
