Mame Push Pull Spinners

[alexportugal1212]

Hi, how many games are there that use push pull function for the spinner, like DOT and Forgotten Worlds, just checking if its worth getting a couple of these spinners.

Also there were other games like Sheriff, Fronline, Tinstar that used a "special" kind of spinner which act like a 8 way positional joystick, meaning that there was a switch for each position and by changing the switch you were able to aim in that direction, plus pushing the spinner down fired, do you know any option to buy one of these?

Push/pull spinner only adds 4 5 games: Discs of Tron, Zwackery, Forgotten Worlds, and Kozmik Kroozr.
EDIT: Eco Fighters also uses a push-only spinner like Forgotten Worlds. (Option added in MAME 0.169.)

Also there were other games like Sheriff, Fronline, Tinstar that used a "special" kind of spinner which act like a 8 way positional joystick, meaning that there was a switch for each position and by changing the switch you were able to aim in that direction, plus pushing the spinner down fired, do you know any option to buy one of these?

AFAIK, the only six games that used this type of controller are:

  Bandido (rotary switch, clone of Sheriff)
  Frontline (Taito Aim-n-Fire)
  Sheriff (rotary switch)
  The Tin Star (Taito Aim-n-Fire)
  Western Gun Part II (rotary switch, clone of Sheriff)
  Wild Western (Taito Aim-n-Fire)

   

The knob turns a cam that presses either one (U/D/L/R) or two microswitches (diagonals) at a time.

If you can't find one for sale on KLOV, you might be able to design and 3d print one.

Here's a preliminary design for a 3-D printed version.

"Fixed washer" = fastened to shaft.

Smooth the ends of the 140 degree arc into a ramp so the microswitch nubs don't catch on them.

The reasoning behind 140 degrees is that the diagonal should start to register about 1/2 way between 0 and 45 degrees. (~20 degrees)

If the center of the wide spot is at 0 degrees, the right edge is at 90 (next microswitch) - 20 (how far it turns before that switch registers) = 70 degrees.

Mirror that for the left edge ==> 70 * 2 = 140 degrees.

Oh wow thanks for such a complete answer, i was thinking of getting couple of those push pull spinners but only for 4 games, and 2 being not much great (DOT AND FORGOTTEN rules), in your opinion you think its worth getting them?

About the other controller-spinner im gonna have to be looking for one then, but again you think its worth it for 4 games?, since 2 out of the 6 are clones

[PL1]

you think its worth getting them?

Worth it for you or worth it for me?   

You're the only one that that can answer the first part of my question.
