First of all, huge TY! I used iBochs on a first gen iPad and successfully ran Linux, Windows 95, and DOS on it. I’ve tried a few times to modernize that code for current iOS releases, but was unsuccessful. I did spend a bunch of time back in the day building a nice UI for iBochs so would be game to help do that for UTM. My contact info is in my profile if you are still looking for folks!
