Touch Input

Keyboard

The on-screen keyboard reflects the keyboard of the emulated computer in appearance and layout. Simply touch a key to press it.

Joystick

The virtual joystick overlays the emulated screen.

The left two-thirds correspond to the stick: it is centered wherever you put down your finger. Drag in whichever direction you want to press the stick.

The right third is the fire button, touch to press.

Mouse

The virtual mouse overlays the emulated screen. It works similar to a trackpad on macOS.

• One finger tap for left click.
• Two finger tap for right click.
• One finger drag to move the cursor.
• Two finger drag to right-drag (move the cursor with right button pressed).
• Three finger drag to drag (move the cursor with left button pressed).

While dragging, you can move one finger to move the cursor, and you can also release one finger without ending the drag. This way, you can keep one or two fingers down while moving the cursor with the other finger.

Paddle

Drag left/right in the lower part of the screen to rotate paddle. Touch the upper part of the screen to press fire.

Light Pen / Light Gun

Touch the screen to put the light pen on the screen or aim the light gun at the screen. While one finger is touching, touch with a second finger to press the button or trigger; touch with two fingers to press the second button.

Hardware Keyboard

Hardware keyboards are supported. Keys are mapped symbolically (they produce the corresponding character) rather than positional. Keys not present on a modern keyboard use the following keys instead:

• Tab for Run/Stop
• \ for Restore
• Escape or ` for ←
• Globe or Caps Lock for C=
• Home or Command-Delete for Clear/Home
• F8 for Help (C16, C116, Plus/4)

For keyboards without function keys, use Command-1 through Command-8 for F1 through F8.

Apple Pencil

The Apple Pencil acts like a normal touch. Multi-touch gestures do not work, since you cannot mix Apple Pencil and finger input at once.

For Light Gun / Light Pen, press hard with the pencil to press the button or trigger.

MfI Controller

MfI controllers are supported.

Joystick

Use either the dpad or the left thumbstick to move the stick. Press Ⓐ for fire, Ⓑ for up (which is often used for jump), Ⓧ for fire 2 (on the Cheetah Annihilator).

Paddle

Rotate the left thumbstick to move the paddle. Press Ⓐ for fire.
