There was some use of self-modifying code, although I can't find exact references. It'll be on Raymond Chen's blog somewhere.

I don't think it should matter whether the original source was VC or not, and if you write a solution that does make it matter you'll find yourself tripped up a lot. (Your favourite game turns out to have been compiled with Watcom or Borland rather than VC, etc). Presumably if you could find the 16-bit VB interpreter bits and pieces you could run those too and run your VB app.

I did run across this blog post http://discuss.joelonsoftware.com/default.asp?joel.3.607174...., which could be turned into a Win10 complaint with a simple search-and-replace.

Some compatibility craziness, that isn't quite relevant to our win16 emulation case: https://blogs.msdn.microsoft.com/oldnewthing/20071224-00/?p=...
