It’s an inspiring work. I’m a man from least background of computer science and assembly language. Even though your demonstrations are really working because of it’s clarity. That’s because you’ve an overall vision to guide beginners in the world of reverse engineering. Hey one personal request: where can I get get your ollydbg.exe that shows red arrows for jumps. I desperately need it. I feel it as the most convenient way to visualize jumps. olly, the one I’m working with is from your zipped archive downloaded from tutorial 3 package. Help me..

Thank you for a very well written tutorial.
Moving from a different debugger and into Olly was very challenging but you SIR made the transition enjoyable.
Thank you,
Kon

Just for the record I find all of your tutorials hilarious and well done. If you wrote a book I’d buy it in a heartbeat (unless it doesn’t have sarcasm and smiley faces then I’ll have none of it!).

Again thank you for the tutorial. I like the little homework section that has us expand on what we’ve learned in this tutorial as well as previous ones. A great example to start off for those of us who are new to this.

I unfortunately also couldn’t understand this:
[quote]Well, we can clearly see in the EBX register that the far right byte (BL) is not 61h, but instead is 31h, so already we’re stuck and we’re going to take this jump that we so much did not want[/quote]

Hello, great tutorials! I would like to ask why my Ollydbg doesn’t show the yellow and blue colors on Calls and Jumps? I’m also really interested in the answer of the homework.
