Hola amigos aquí les dejo el código fuente del crackme1 de dyablo, como siempre esta hecho en vb.net
1- Agregamos 2 TextBox el primero llamado txtnombre y el segundo llamado txtserial
2- Luego agregamos 5 Button llamados
Button1 con la propiedad text igual a Copiar
Button2 con la propiedad text igual a Refrech
Button3 con la propiedad text igual a Copiar
Button4 con la propiedad text igual a Generar
Button5 con la propiedad text igual a Parchar Boton
3- Después agregamos 2 RadioButton uno llamado op1 y el otro op2
4- Tambien agregamos un Timer llamado timer1
5- Por ultimo agregamos 1 Label llamado msj y con la propiedad text igual a "Keygen Crackme 1 De Dyablo By Flamer "
También se me olvidaba tienen que agregar un archivo mp3 a los recursos para el sonido del keygen
