Hi there!

I've the opportunity to get an old w16 program to run in a dosbox environment.

So far so good, Win31 is running, the program is starting and my dosbox-parallel-port emulation is giving me the all read/write operations to the parallel port.

I'm aware that HASP3 is totally broken and I already found http://www.woodmann.com/fravia/bayu_2.htm.

The problem now is that this might help you dumping a dongle but for implementing an emu some parts seem to be missing...

Does anyone know a more detailed description of the low-level-IO stuff, the statemachines inside the ASCI,...?

cheers,

little update... now digged into the dosbox source... the debugger seems adequate for some deeper debugging and stuff.

I found that my target only uses HASP service 1 and 32...

Since I did not get some reasonable deadlisting, I no throw a breakpoint on each hasp-init (0xC6) received to get directly into the section where hasp does its magic.

This is very different to what i get with w32dasm... so I transplanted the memdump into the original file and voila, much better results...

Now it's ASM reading time...

cheers,
