Pardon if my search terms have been failing...
Is there a time-traveling debugger/emulator for NES? Or some such similar functionality with regular state snapshots that you can revert back to?
I see that Mesen will let me step backwards one instruction at a time, but maybe I'm missing more advanced functionality?

I think Mesen has rewind, I wonder if that's what you're looking for?

Re: time-travelling emulator?
Thanks! Oh, interesting - found the keybinding for it.
Hmm, it triggers uninitialized memory read - probably a bug. Seems somewhat limited, but better than nothing.
It also has an automatic state save mechanism, but can't be set to faster than every 1 minute. And can't rewind from the state.

Ok, took me building Mesen from source to figure out that "movies" are actually state movies which are debuggable! And that the history viewer can let you scrub and select a state to resume from.

You might also be able to use other emulators with re-recording support?
Re: time-travelling emulator?
Ah, that's a new term for me. Interesting. Looks like FCEUX supports this.
Thanks!
Thanks!
