This tool relies on the use of a low-level programming language called assembly language (asm) to discover all the connections between compiled code and machine code instructions that are powering the computation ability of modern CPUs that power our home and business PCs. By observing the way the target application is talking with the CPU, it can detect all of their interactions and translate machine language queries back into the assembly language. These observations can help programmers to learn the inner functions of unknown software, reverse-engineer its source code, and find out how it all works.
It has a built-in support for disassembling code of wide variety of files, including formats such as .exe, .386, .com, .cpl, .dll, .drv, .fon, .mpd, .ocx, .vbx and .vxd. During and after the disassembly procedure, users are encouraged to save their findings and create projects that can be resumed at a later time. The app can easily handle 32-bit disassembled executable files of all sizes.
- Disassembles Both 16 and 32 Bit Windows Programs
- Displays for Exports, Imports, Menu, Dialog, and Text References
- Integrated Debugger for 32 Bit Programs (16 Bit Debug Not Available)
- Includes Text Search and Navigation Functions
The user interface of the app is intuitive, but it is crowded with a large amount of machine language monitoring and disassembled code tools. To streamline the process of the disassembly, developers of W32DASM from the software house URsoftware have included helpful tools such as Search function, smart implementation of instruction pointers, break/load DLLs, thread creation/exit monitoring, execution of jumps and calls, examining of data objects and segments in a hexadecimal display, and even searching of function lists that can be imported/exported. The app is not directly configurable (even keyboard shortcuts are fixed), but it at least supports the ability to change its main font.
W32DASM is an old application that is not actively upgraded anymore, but it still provides extensive toolset needed to accurately and reliably disassemble and reverse-engineer compiled code. It is 100% FREE and can be used on all versions of Windows OS (due to its age it is not optimized for newer versions of Windows, but the app works fine even on Windows 10 and Windows 11).
