That "other" MAME debugger |

That haircut is on point.

I did notice that the -rewind switch was after the -debugger entry you added. It shouldn't matter at all, but personal experience suggests it might be worth trying the -debugger switch as the first then last option in the list just to confirm it's not something flaky like order of operations. Also, those weird double characters - was that worth an ini delete at that stage? I don't think you tested that eventuality either. Good luck!

Thanks for the suggestions! First off, I later discovered the QT debugger DOES support rewind, it's just that there's no menu or kbd shortcut. You have to type the "rewind" command explicitly in the console window each time you want to rewind, and it seems to work fine! As for the extra characters, deleting the .ini does not help. But removing "-natural" from the command-line does fix that problem. I guess that's a clue of some sort, but haven't investigated further.
