Along the same vein as MAME/MESS/UME, it would be such a lovely thing to allow for:
1) an overlay, such as a hires C= PET, 1702 / 1802 / 1902 monitor to frame an emulator's video rendering
2) cpu/monitor/disk LED(s) coordinates that interact with any on-screen indicators with emulator peripheral activity
I'd like to take this one on myself, having hacked around a bit in the code, but it looks like it could be a more trivial task for a VICE developer. What can I do to help make this happen?
