I'm thinking one of these in my new project with an octogon restrictor. I was gonna go servostik and hack it into the ArcadeSD for switching, but I think the feel of this over the servostick will be the way to go. Still kinda on the fence.
IMO, 4-8 way switching is overrated when using a modern MAME build. I wish I hadn't bothered with it in my cab and am thinking of removing it.
(mine is an oddball, as it reduces the sensitivity of the optical switches instead of moving a physical restrictor. Same round restrictor either way)
MAME doesn't allow two directions to be triggered simultaneously anyway, it reacts as if only the most recent switch is being pressed.
So maybe the change in direction would register sooner than it would on a 4-way, but I'd think that would be a good thing.
I didn't do any better at the games with the joystick in 4-way mode.
When testing to see if an overlap or a gap between 4-way directions would be more preferable, an overlap was better.
I didn't know it at the time, but MAME was eliminating the overlap and making an instant transition anyway.
Some people say they just like the feel of the diamond pattern restrictor when playing 4-way games.
I can understand that. Especially with a square restrictor where you have big corners.
...but my next build won't bother with it and I am considering removing it from my current build.
It's just one more thing to go wrong. To keep the circuit simple, mine had to default to 4-way.
It sucks when you launch USSFIVAE and the joystick is in 4-way mode because there was some hiccup with a script.
