OllyDBG v1.10

Special highlights are:
– 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
