The script was on github. url : https://gist.github.com/fritschy/1183292 And I got two results, one is before applying this patch, another is after doing that. These are possible to compare but it has difference of base address... I'm not sure what should I do for applying this patch. :-( If anyone knows how to compare, let me know. Thanks.
