Adding a code into a program


thankx to author (quên mất tên tác giả rồi :JEZYK1: )

Khi dùng Olly để trade, các bạn thường sẽ thấy những đoạn code DB 00. Đây là
những "phần thừa" của chương trình mà ta có thể tận dụng để làm việc gì đó
(chẳng hạn như ghi tên mình vào).
I - LÝ THUYẾT :
Trước hết, tui xin nêu khái quát 1 vài điều về cách làm này :



Chúng ta sẽ tận dụng đoạn code không dùng tới để đặt vào đó đoạn code của mình
:



Sau đó chúng ta sẽ cho chương trình nhảy đến đoạn code của chúng ta bằng lệnh

jump :



Xong ta sẽ cho "nhảy" ngược lại về điểm đầu của chương trình :
