State saving and recovery is not good when using a smart drive about apple2js HOT 4 OPEN

Can you give a particular example? Is this about the state of the drive or about the state of the whole VM?

Below is the game I am making.

If you save the state with F6, move around a bit, and then load the state, it doesn't go back to the original state.
I haven't written any files, I'm only reading from the .hdv.

I hadn't implemented saving state for the smart drives because the naive approach of just storing the whole images that is use for floppies doesn't work with the larger disk images, because of browser local storage limitations. But I had been contemplating storing block deltas, and that would work as long as the hdv that gets loaded doesn't change. There are also possibly ways to store more data other than using local storage.

The game you are working on looks great, so I hope we come up a solution that works for you.

Storing the delta seems like a very good idea.
Thank you very much. Your work helps me a lot. May you always be happy.
