I decided to post here instead<br>before venturing in (:<br><br>So, having learned this the hard way, there are a couple of strategies I could take--RFB, or maybe Nebraska-- to get events over to<br>the target image but before doing that I have to ask is it really necessary? <br><br>My goal is to port the StackInterpeter to native 64 (and after that 64x64). Presumably Eliot managed to do the original work without the<br>use of direct interaction with morphic on the running world, so shouldn't my task now be to emulate whatever techiques Eliot uses?<br><br>If so, that raises the final point. What exactly are those techniques? Specifically, given a running simulation, how does one produce<br>a new VM? Do we boot up the target image on which we have developed and run VMMaker the standard way?<br><br><br>Finally, direct interaction with the runnig simulation world is desirable, I will be happy to implement it. Just please inform me of what strategy you would prefer and I<br>will try to get it done.<br><br>Thank you for your time.<br><br></div></body></html>
