The VS-Debugger is no replacement for the dosbox debugger.
The latter is capable of debugging the dos-applications (in
your case BC4/VC1.5) and supplies additional information
like unemulated aspects.
If you can provide either debug logs of the dosbox debugger
running the program, or examples (like the executables needed
to reproduce the problem, but be aware of copyright issues)
it might be possible to fix it.
