* Configurable disassembler, supports both MASM and IDEAL formats * No installation - no trash in registry or system directories * Open architecture - many third-party plugins are available * Saves patches between sessions, writes them back to executable file and updates fixups * Understands debugging information in Borland速 format

* Allows for user-defined labels, comments and function descriptions * Object file scanning - locates routines from object files and libraries JCode, which supports parsed binary code, has the capability of providing data to you even when your location is unavailable. By examining the threads and code, it can guide you in the right direction. * Code analysis - traces registers, recognizes procedures, loops, API calls, switches, tables, constants and strings OllyDbg is a program designed to debug multi-Codes are analyzed and the information is displayed as part of thread programs. * Intuitive user interface, no cryptical commands OllyDbg is a 32-bit assembler level analysing debugger for Microsoft速 Windows速.
