From time to time I will publish an updated version of Stockfish with these features. Or maybe some known derivative will include it.

It will be excellent!

Thanks for your contribution, anyway.

Is asmfish with option TTF-file one of the derivates with hash saving capability?

I tried it less than one minute. AsmFishW resets its hashes every time you make a move. I never tried to save/load them because I think a hash which only keeps its contents until a move is made is rather useless for game analysis. They are "non-persistent" hashes.

What? Are you using a GUI? Without looking at the code, I can't say what would trigger hash clearing in asmFish, but what you've claimed doesn't make sense to me.

Of course I use a Gui... Don't ask me to use an engine in console mode!

Arena Gui. Click "Analyze" and it's in infinite analysis. You'll see hashfull % raising to 99%, sometimes 100%. Then try making a move. Hashes start from 0%.

Then, try Stockfish "Savehash" version by Daniel. Uci option "Never clear hash" checked on. Click "Analyze" until hashfull is 99% (or 100%). Then try making a move and you'll see there's been no hash reset.

I hope this makes some senses....

I have no idea what UCI commands Arena sends to an engine when you "make a move", but, in any case, that would be an issue with the GUI, not with the engine.

And doesn't hashful simply report (approximately) the amount of hash utilized by the current search? So, of course, it starts at 0, but that doesn't mean the hash was cleared at the start of the search.

Yes. it is.
