Avoid multiple detect from single12way rotate

[zorro2055]

Hi @mahoneyt944 ,

This is the same patch that I did for mame2003-plus, adding the "X-Way Joystick" option to the Analog Controls menu only for IPT_DIAL and IPT_DIAL_V devices. Enabling the X-Way Joystick option eliminates one rotary step of a X-Way rotary joystick from sometimes rotating the character 2 rotary steps.

This basically combines the codes used in these two PRs in mame2003-plus: https://github.com/libretro/mame2003-plus-libretro/pull/1652 https://github.com/libretro/mame2003-plus-libretro/pull/1740

It has been about two weeks since those PRs settled, and I didn't see anything mentioned in the issues list, so I assume no bugs have been discovered.

Also, question for you. Is there a good place to put recommended key/joy step, sensitivity, and x-way joystick settings for each of the 15ish or so games that used a x-way rotary joystick? I figured out what the specific settings that work best for each game with an x-way rotary joystick. I'd be interested to add that in a blog or faq somewhere so people know about it. I'd want to add that for mame2003 and mame2003-plus. If that is not possible, I do plan at the least to send that info to the manufacturer of the 12-way rotary joystick that I have.

Thanks!

@zorro2055 well idk about noting it here, but you can in mame2003+'s CHANGELOG.md, just add an input section or at the bottom.

Thanks @mahoneyt944 . I'll add that to CHANGELOG.md in a new PR as you suggest and will post it here for good measure.

Posting description of X-Way Joystick option and recommended analog controls settings here for X-way rotary joystick games here for reference.

• Added 'X-Way Joystick' Option to Analog Controls Menu only for IPT_DIAL and IPT_DIAL_V devices. This option is for use with x-way rotary joysticks (where the joystick can rotate X discrete steps, 8 or 12 appears to be most common). The joystick can still move up, down, left, right and diagonally. The most famous game to use this control scheme is Ikari Warriors. Notes on this option:

  • When on, prevents the character from rotating two discrete steps sometimes when the rotary joystick is just rotated one step.
  • When on, the character will only rotate up to half the frame rate instead of the frame rate, so up to 30 times per second instead of 60 times a second if the game is running at 60Hz.

• Recommended analog control settings for known games that use an x-way rotary joystick to give the intended rotary control of the character. (Note: Settings will work best if the game is running at its native 60Hz, and the time the rotary joystick "holds" down the virtual IPT_DIAL or IPT_DIAL_V button is longer than 1/60th of a second, but less than 2/60ths of a second.):
