Description
Would it be useful to have a standard mechanism for this, or is it enough that users can, for example, check disasm at PC for the halt instruction? My initial concept for this is for MainForm to check IsHalted after calling FrameAdvance, and if it becomes true, using the most recent framebuffer for all subsequent redraws (freezing the video output) and indicating a halt on the status bar. Basically the frontend behaves almost the same as is it were paused.
Another thing I'm not sure of is whether a simple boolean is sufficient. Is there a console with several distinct halt/crash states?

Research direction
Start by reading the IEmulator.IsHalted proposal alongside MainForm and the FrameAdvance flow. Compare it with checking disasm at the PC for a halt instruction, and consider whether a boolean covers the distinct halt or crash states mentioned. Done would require an agreed API design and defined frontend behavior for the framebuffer and status bar.
