This is limited to DOS, text-only applications because pcemu does not support windows or graphics. Other than that, you might try using a Logic State Analyzer hooked at the parallel port. > BTW: Is it illegal to trace this kind of data and publish it as C-kode? I really don't know. Usually Terry has an answer for everything...
