in the spectrum emulator certain keys (Q A O P dont know if others) doesnot work in any device i asign to. for example i configure to the first controller those keys on the DPAD (Q to UP, A to Down, etc) but later in game it doesnot work. i try to press those keys on virtual keyboard and doesnt work neither
Sorry, I haven't used DidntxSpectrum in years (I much prefer FuseX, which I'd recommend you to try), but it sounds like the joypad might already be configured to use those keys (for the Kempston joystick emulation, or something), so try looking through those options.
Good luck, and consider trying FuseX, as it really is excellent.
