Working on a software from:

The software is written in VB3 and protected by a 16bit DLL called keylib16.dll.

I have found out that the function pp_tcode returns a value that opens upp the software.

I have tried to load the dll in winice.dat but I cant set a breakpoint at the function inside the DLL.

The symbol loader tells that there is no debug info.
Is there another way that I can produce a NMS file for the 16-bit DLL?
