I need to replace a faulty motor on one of my motorized 4-way/8-way restrictor plate switching joysticks...

...except, I can't even remember where or when I got these or what they're called.

A little help?

Thanks!

It's an Ultimarc Servostik.

Couple of dedicated bootlegs I’ve made.  Armed with snips and a lot of hot glue, you can make these pi pico PCBs work in original shells.  Usual shipping label crap run through the printer.  No one will notice or care.



Actually a fun game, one I hadn’t heard of before.  Apparently fairly rare.  I trashed a copy of Atlantis I paid 40 cents for.



I remember them advertising the hell out of this one.  Not entirely sure what’s going on but eh.

Could you elaborate more on which games were only released in PAL?  I’m useless to answering your questions.

I've built myself a cabinet with joysticks only, but am now looking into ways of enabling driving/paddle games and those with a rotary joystick for aiming as well, on a small-sized control board.

My holy grail would be a single upgrade for all of them.

Is there a way to do this without a dedicated spinner? Am I hunting for a unicorn?

If you're trying to cover all of the games in those categories, you are indeed hunting for a unicorn.

You can find some control combinations that will work well enough for some of the games, but there will be compromises and some games like Arkanoid will never play well without a dedicated high resolution spinner.  What games are on your "can't live without it" list?

You may want to look into this GRS rotary joystick.
- It has switchable modes/handles for the "clicky" games like Ikari Warriors (mechanical rotary games) or "non-clicky" games like Caliber .50.
- It also has push/pull switches for games like Discs of Tron and Forgotten Worlds.



You will need to configure your settings in MAME, especially for the mechanical rotary joystick games.

Hello everyone,

Some SNES and Mega Drive (Genesis) games were only released in PAL format, and I want to emulate them on a CRT with proper resolution and aspect ratio using super resolution and switchres.

Switchres often calculates a 244p or 240p resolution (don't remember), but either way, the image appears squashed. The only way I’ve found to fill the screen correctly with the correct aspect ratio is using 288p. However, this introduces jitter — the image slightly wobbles or shifts, like a sync mismatch.

According to ChatGPT:

In PAL, the signal is transmitted in two fields of 312.5 lines, which together form an interlaced frame of 625 lines. When using progressive scan like 288p, the full image is sent in one go, removing interlacing. This totals 312 lines (288 visible + sync/blanking). If this total is altered (e.g., to 313), some TVs interpret the signal as interlaced, causing jitter.

Following that advice, I tried ensuring both the RetroArch-generated modeline and the VMMaker-installed one use exactly 312 lines. This helped reduce the issue slightly... in SNES Asterix PAL, it sometimes works perfectly, but other times it doesn’t, jitter still appears in other games – sometimes more, sometimes less, and sometimes in different screen positions, upper part or lower part.

My Setup:

• GPU: Sapphire Radeon HD 5450
• CPU: Intel NUC13ANBi5
• OS: Windows 10
• Drivers: CRT Emudriver 2.0 + VMMaker
• CRT: Sony Trinitron KV-21FX30E (EU model)
• Resolution: Super-res 2560x288 @50hz

Question:
Does anyone know what might be causing the jitter I'm seeing in some PAL games 288p? I'd really appreciate any insight into why this jitter happens and how to fix it.

Thanks in advance! 🙏

I designed mine to nearly the same dimensions as you, though less deep (425mm) : I had to put in weights so it wouldn't tip over.

For screen/control board angles, my aim was to accomodate persons between 5"/150cm (my spouse) and 6"/180cm (me).
I tilted the screen so that a person in middle of the height range would have their line of sight perpendicular to the center of the screen.
I tilted the control board just enough that a person at the bottom of the height range could have their wrists lie flat on it.

I agree that screen tilt should not have any impact on light gun aiming.

Hello,

I've built myself a cabinet with joysticks only, but am now looking into ways of enabling driving/paddle games and those with a rotary joystick for aiming as well, on a small-sized control board.

My holy grail would be a single upgrade for all of them. I had originally spotted this : https://www.ultimarc.com/arcade-controls/joystick-accessories/ikari-12-way-rotary-upgrade-for-servostik-j-stik/, but (correct me if I'm wrong) this rotary upgrade is :

• Not continuous ("Rotary movement issues a keystroke or gamepad button press for each of 12 clicks")
• Has only 12 signals per revolution, which is way lower than most numbers found here : https://wiki.arcadecontrols.com/index.php/Spinner_Turn_Count
  

... making it useless for anything other than aiming.

I expect that :

• a separate spinner could be OK for driving/paddle, but clunky for aiming;
• aiming can be replicated with buttons.

Is there a way to do this without a dedicated spinner? Am I hunting for a unicorn?

Thank you

Hydro Thunder Hurricane now works in a WIP branch - at least for two players. I will check up to 8 later and report back.

I am getting an open circuit when measuring across the blue component.

My temperature probe is unfortunately not working. The readout stays on 80*F no matter where I place the probe. I will need to get a replacement.
