Hello,

First, thanks for this awesome software, I know it's not very specific to games, but dosbox already help me to develop/debug an home made ISA card I've build to play with electronics 😀

I have a question about memory dump : is it possible to dump to disk executable's image in memory to disk with cpu registers contents after n instructions ? like run foo.exe, run 200 instructions then dump memory to disk ?

cheers,
Loic

To play with my ISA card. I'm trying to set/get various bits.

For the moment I'm only playing with simple logic gates, and I'm very happy to see that I can read on my card the result of a very simple 'electronic' operation like 0 AND 1 makes 0
