Yes, if you need tune it this way, then you really need widget. I will think about it tomorrow, but next version will go out soon, i wont include it there, it must wait for v72
Are you sure that your expert settings are ignored? Because it always worked. To be sure, find appropriate profile folder in .MagicBox/Games/Data and in temp folder is generated dosbox config which is used for current profile session
Btw, do you need tune cycles manually if you set in expert setrings cycles=auto? It should adopt. Or maybe you can try cycles=max 50% or similar option, they are well described on dosbox official webpage
