Real Understanding Of Serial Generation

there are keygen useless because online checks, sometimes cracked/cracks are better than keygen and maybe done easier than cracking.. newbies cracks in the way change 74 for 75, experience crackers injects code /IAT and maybe rebuild all exe file or dll in some way, makes code redirection and kills crc checks, so i don't believe that could be boring to play with some code and do it in your own way , at the end a 'good' crack will do the same as keygen and maybe better if cracks says enter any code to register and any name
