EVERYONE uses 8-Way Restrictor Gate for Fighting Games.
It is impossible to play with 4-Way.
You’ll only be able to Jump, Crouch, Forward and Back.
You’ll only be able to do Charge Moves like Flash Kick and Sonic Boom.
Can’t even Block Low.
Square and Octagonal are both 8-Way.
4-Way does not mean Square, but a Square can be 4-Way.
Pro and Con of 2-Way, 4-Way and 8-Way?
2-Way only moves LEFT and RIGHT, or UP and DOWN.
Games like Space Invaders, Galaga and Galaxian use control only moving left and right.
4-Way moves UP, DOWN, LEFT, RIGHT, or UP-LEFT, UP-RIGHT, DOWN-LEFT, DOWN-RIGHT.
Games like Pac-Man, Donkey Kong, Frogger; going up and left and right and down.
8-Way moves both ways of a 4-Way, so eight directions.
UP, DOWN, LEFT, RIGHT, UP-LEFT, UP-RIGHT, DOWN-LEFT, DOWN-RIGHT.
Michael Jackson’s Moonwalker, Metal Slug, some Shmups, Street Fighter; 8-Way.
I don’t really know how to Pro/Con between 2-4-8-Way.
They are so different to each other.
Something else to say.
A lot of people confuse and get wrong about Square and Octagonal Restrictors.
Square has four sides, and Octagon has eight sides.
So Square would be 4-Way, and Octagon would be 8-Way, right?
The Sanwa JLF comes stock with Square Restrictor.
The Square is an 8-Way, so is the Octagonal Restrictor.
Both go UP, DOWN, LEFT, RIGHT, UP-LEFT, UP-RIGHT, DOWN-LEFT, DOWN-RIGHT.
But the Square can also be turned into a 4-Way.
This goes only UP, DOWN, LEFT, RIGHT.
If look close at the stock Restrictor, you will see that it is made of two parts.
Outer Ring clips onto the Joystick, inner is the actual restricting part.
Rotating the Inner Ring clockwise will turn the 8-Way into 4-Way.
Do it by pushing the Inner Ring with pegs facing towards you, then turn.
