Well, it depends what you define as our core target :-) I think we get quite a lot of users that want some useful ability to see what their guest code is doing, and these days (when dev board hardware is often very cheap and easily available) I think that's a lot of the value that emulation can bring to the table. Obviously we would want to try to do it in a way that is low-runtime-overhead and is easy to get right for people adding/maintaining cpu target frontend code... thanks -- PMM
