I believe there is some kind of problem with the keyboard on the Apple II core. Karateka is impossible to play with the keyboard and even Joystick is working a little slow (but it's working). If I press "k" for keyboard, the fighter only executes a punch or kick after 5 seconds or so. Pressing "J" the joystick takes places and it´s possible to play again.
I already tried several disk images and the same NIBs on Applewin emulator works great with the keyboard.
