Wintruder is a user mode debugger for Windows 9x and XP. I started writing it some time ago. But I think it will never reach a final state since I have more ideas than I have time. Nevertheless, it’s grown enough to be shared here.

Debug interfaces:

Win32 Debug API [Intel x86, VisualBasic p-code, Virtual Dos Machine]
Win32 Stealth [Intel x86, VisualBasic p-code, Virtual Dos Machine]
Microsoft .Net [.Net CIL]

I don’t know what to write about features, so I better write about problems:

The code analyser is rather weak.
The use of debug information is limited to bare function definitions (and sources if available).
The native .Net debugger is missing.
The script engine is not really working.
The Stealth interface has been tested on Windows XP SP2, SP3 only.
You better use an auxiliary monitor when debugging VDM full screen applications.
You may encounter several bugs and deficiencies…
