Looks nice!
Just a question: How do you get the address of an instruction from OllyDbg, if I want to make a patch, for example?

Anytime I needed that I used an external program to get section's file offset and then the resulting file offset was section_file_offset - section_base_address + instruction_address. Other method that I use more frecuently since requires less brain power is just open the hex editor and search for a pattern, if the pattern is found more than once then I try again with a bigger one until there is one occurrence, that occurrence is the file offset we need.

Anyway, remember that OllyDbg allows you to patch the executable and write the modifications to it (right click, Copy to executable > All modifications).

Last update: December 25, 2007

The last available version can be downloaded here. Don't expect too much, use v1.10 for any serious work. Don't send me requests for features already available in v1.10. Please report only serious bugs and crashes. And, of course, new ideas are always welcome!

Pre-alpha 3: many different features like attaching to running process, detaching, run trace (as yet without fast stepping), real-time stack analysis, recognition of TLS callbacks, guarded memory, intermodular calls etc. Look at the comment column in the list of calls - you will enjoy it!
