Right, as I have a mega ste and not ste and a falcon, I'd go with implementing all 3 but probably keymap al all fire buttons on the keyboard so as not to have to move your one hand from joystick to kbd all the time. If you have an airplane type of joystick it's ok but many prefer arcade type joysticks.

Does the mega STE not have EJP's?

CJ suggested a Coin-Up mode; Joystick for movement and zxc for fire buttons.  However, this would only be usable if your joystick has suckers (like you say), so Tomchi was interested.  After all, any sensible Atari owner has either a JeST or Konix Speedking or a Cheetah Bug ;)
