Hi!

This list is for discussions about the development of the emulator,
not about general usage. You can use the Help forums for that:
https://sourceforge.net/p/fuse-emulator/discussion/

But I think we actually have a bug, so I'll take the opportunity to
share the details :-)

First, the answer for your question:

Three Weeks in Paradise does not support the cursor keys or cursor
joystick, but you can emulate a joystick using your computer's arrow
keys:

$ fuse --kempston --joystick-keyboard-output 2 --joystick-keyboard-up 256 --joystick-keyboard-down 257 --joystick-keyboard-left 258 --joystick-keyboard-right 259 --joystick-keyboard-fire 32 -m 128 ThreeWeeksInParadise.tzx

Once the game is loaded, select "2. KEMPSTON" from the game menu. The
controls are the arrow keys and space to jump.

Now, for the rest of the team:

The "Configure joystick" dialog allows mapping Spectrum keys (enum
keyboard_key_name) to the joystick controls but then the native keys
(enum input_key) are the ones actually used.

Two ways to see that:

1) Emulate a cursor joystick and use code 274 (INPUT_KEY_F8) for the
   fire button:

   $ fuse --joystick-keyboard-output 1 --joystick-keyboard-fire 274

   Press F8 and you'll see joystick fire ("0") on the screen, although
   F8 is not a Spectrum key.

2) Open Options -> Joysticks -> Keyboard, select "Cursor" type and
   Button for FIRE -> Enter.

   Now if you press ENTER you should see joystick fire ("0"). Instead
   you'll only see that if you press Arrow Up.

   And this is because INPUT_KEY_Up == KEYBOARD_Enter == 0x100

Ideally for joystick emulation it would be more natural for the user
to choose native keys but that's not what the dialog shows.
