From the web page: DSM Studio is a application to aid disassembly and inspection of Windows based executables built for the Intel x86 architecture. It is still in the early stages of development but may still be of some use to tinkerer's or anyone who is interested in the art (or science) of disassembly. Some of the most important features are:

• API Call Detection: detection of WIN32 API calls and conversion within the listing
• Resource Viewing: Accelerators, Bitmaps, Cursors, Icons, Dialogs, Menus,Version, Custom (Hex View)
• Import / Export Functions: Listing of DLL imports & module exports
