Question about BeaEngine [delphi]

[ding]

Hello,

I have BeaEngine unit source in delphi , which i've found quiet useful since I love low level stuff and I hope I will be able to code my own debugger oneday .

It's hard to understand the code , @kao if you can please explain to me how it works since you've updated this unit , my other question is :

does all debuggers and disassemblers use the same methodology ? 

I started reading Intel manual but my native language is not english therefore it's hard to understand each line . are there any alternatives ?

all I did was making a simple diagram to avoid complexity because records are nested .

 

 

after steping , The EIP doesn't point to the address of the first instruction ? also , I don't really understand how CompleteInStr got filled with Push edi  .

Hi Ding,
I just fixed some (obvious) issues with the Delphi interface, I didn't write the complete unit. So, I'm afraid I can't answer your questions.

Cheers,
kao.

I found this paper , it has some useful informations but it's incomplete , I guess the author stopped here ! and didn't bother to release others parts .
