- The Essay
-
- As this is a tutorial for newbies, I'll go into details about how I go
- about cracking the program. I suggest that you read this tutorial first.
- When you have completed the tutorial, leave this tutorial open and follow
- the instructions. Re-do it once more after you have completed the step
- by step guide...
-
- In this essay, when I write type "d EAX" or similar commands in Softice,
- I mean it without the quotes.
