The application I'm trying to reverse engineer intentionally executes unsupported opcodes, and some of the code is executed by a handler.
Step Into does not follow inside the handler.
I know that the handler address can be obtained by setting a breakpoint in ntdll.
Code:
ntdll.RtlUnwind+448 - mov edx,[ecx+04]

But is it possible to achieve continuous tracing using Cheat Engine or another application? Something like
Code:
app - working code
app - broken code
handler - code
app - after broken code

There must be some other OS code around the handler, like ntdll.KiUserExceptionDispatcher, so I'm not sure.

CE has a continue unhandled option.

If you're using the windows debugger, place a breakpoint in NtRaiseException before you continue unhandled, and it'll break there and then you can continue stepping

When using the VEH debugger it's a bit more difficult. You'll have to find out the routine that's going to get handled next in advance
