Description of OllyDbg 2.01 Alpha 2
32-bit assembler level analysing debugger for Windows
OllyDbg is a 32-bit assembler level analyzing debugger for Microsoft® Windows®. Emphasis on binary code analysis makes it particularly useful in cases where source is unavailable. OllyDbg is a shareware, but you can download and use it for free
Key features
• Intuitive user interface, no cryptical commands
• Code analysis - traces registers, recognizes procedures, loops, API calls, switches, tables, constants and strings
• Directly loads and debugs DLLs
• Object file scanning - locates routines from object files and libraries
• Allows for user-defined labels, comments and function descriptions
• Understands debugging information in Borland® format
• Saves patches between sessions, writes them back to executable file and updates fixups
• Open architecture - many third-party plugins are available
• No installation - no trash in registry or system directories
• Debugs multithread applications
• Attaches to running programs
• Configurable disassembler, supports both MASM and IDEAL formats
• MMX, 3DNow! and SSE data types and instructions, including Athlon extensions

• Sets conditional, logging, memory and hardware breakpoints
• Traces program execution, logs arguments of known functions
• Shows fixups
• Dynamically traces stack frames
• Searches for imprecise commands and masked binary sequences
• Searches whole allocated memory

Editor's review for OllyDbg
The OllyDbg is a 32 bit debugger at assembly level. It has very powerful capabilities for analyzing and understanding machine binary code. It is a freeware program which can be used free of charge for personal as well as commercial uses. You not only can use it but also alter or make changes to suit your specific requirements as long as you do so under the gamut of the General Public License of GNU. The creators do not support this software with any implied or explicit warranty as to the feasibility or viability for any particular purpose.
The capabilities of the OllyDbg program to analyze binary code make it very handy in cases where the original source code is not available. There are no cryptic commands since it is an intuitive interface. Its ability for analyzes of code includes ability to trace and recognize strings, procedures, constants, loops, switches, registers, tables and API calls. It possesses the ability to debug DLL files by loading them directly in the system. The OllyDbg helps location of routines by scanning object libraries and files. You are permitted to define labels as per your choice and place descriptions of functions as well as to insert comments.
The OllyDbg enables debugging of multi-thread apps and attaches itself even to programs that are in running mode. It is software enabling disassembling which can be configured and helps provide support to IDEAL and MASM formats.
The OllyDbg facilitates the understanding of information regarding debugging in the Borland file formats. It enables patches to be saved between active sessions and also for fix-ups to be updated by writing them back to files that are executable. Since the software is a shareware and comes as an open architecture, plug-ins created by various third parties are also available for your use. The OllyDbg does not require any specific installation and therefore there is no clutter in your system directories or the associated registry.
