Flash loading only works for non-protected tape files and loading noise is either painfully loud or non-existant. It works, but choosing not to blur the screen makes the screen far more blurred than my old 14' PAL TV with HW acceleration enabled, (Nexus 7) so adding scan lines (not available in the clean, but slow software rendering) just makes things worse. This Spectrum emulator comes in last place among many Android Spectrum emulators in my view.
