Droidfish UCI parameters changing

Great idea updating Droidfish to allow changing on specific UCI parameters for every engine.

However, they don't appear to be implementing correctly, or at all, in fact; there is no difference in play when I change the parameters, which leads me to think that the engine is playing on default settings all the time.

I've even tried setting ridiculously stupid values for each certain parameters to make sure I'm not missing something. For example, setting material weight to 1 out of 200 for several engines should make them play like idiots, sacrificing material left, right and centre (I clarified this in Chess PGN Master, the only other Android chess app that allows changing on UCI options). But the engines still play like default.

Am I doing something wrong here? The settings definitely have no effect in human vs engine or engine vs engine mode. Do they apply in analysis mode only? (but that would be strange).

Any help or ideas would be appreciated.

    That was because those UCI options had been deleted in the Stockfish version you had. They won't come back. The GUI authors hadn't updated their GUI to reflect the changes. Therefore, they just sent some empty UCI request which Stockfish didn't understand. Tord's Stockfish, SmallFish and Droidfish all failed to update for the changes so far.

    Thanks for the reply.

    I'm not talking about Stockfish parameters specifically. There was a recent Droidfish update that supposedly allowed changing of UCI parameters for all engines that you added to Droidfish. So I'm talking about parameters that exist for Firenzina, Rhetoric, Black Mamba, Critter, among many other Android engines.

    Droidfish has a new option under Manage Chess Engines to set UCI parameters for the selected engine and displays all the parameters in a menu for you to change. It is these changes that I'm saying seem to have no effect.

    Sorry for the misunderstanding.
