Hey guys. I'll try to answer all of the questions:

1) We didn't rewrite any code. It is %100 emulated. Rewriting the code would have broken the Copyright.
2) You could use two monitors. The problem is the image is inversed to work on the game. You would have to write a hook to correct the image to the second monitor.
3) We actually added a pause feature at one time but it caused way too many problems so we took it out.

We've actually taken a break on new development. Working on it for five years eating up most of our spare time was getting a tad old ;-) We're still supporting it and we are fixing code bugs. A new release should be out fairly soon to fix some really obscure bugs.

Peace.
