im only gonna post this because it might help others.
Im sorry if I offend your level of skill or familiarity, but its best to go basic.
I’m gonna assume this is the only arcade stick you have access to.
Then hold it right there.** don’t even think about modding or “REAL ARCADE PARTS” for now, it’s just gonna confuse you.**
Don’t even think about fighting games for now.
Play something “simpler to control” than fighting games. Since its a PS3 Hori FS V3 stick, plug it to you PC and load up some MAME / emulators / other PS3 games. Play Pacman, play beatemups like Final Fight, run and guns like Metal Slug, or shootemups like Gradius. Random stuff like that.
I don’t mean be good at them or play them excessively, just get comfortable with the joystick. You need to play games where it trains you to know how a joystick itself works. You need to get comfortable with games that still require fast reactions, but doesn’t put you in a position where you have to react with hand-twisting joystick motions. Figure out what kind of setup works best for you, try playing on your lap, on a table, standing up on a pedestal, on the floor. The luxury of arcade sticks these days is that you are not restricted to a cabinet, and you can find a position that suits your comfort.
these kinds of games emphasize the joystick for the most basic of its functions, which is making use of the cardinal directions, the ups the downs, the lefts and the rights and then diagonals. after a while, you might find yourself and your hand adjust to a comfortable position for you. if you find that you found a natural-feeling way of handling the joystick, wherein accessing all directions is easy and becomes second nature, only then you might wanna start doing more complex fighting game-like motions.
After that, Pop in training mode and start moving your character easing your way into doing those more advanced fighting game tech.
just my 2cents.
if you feel that after all that, you’re still comfortable with a controller/pad. nobody’s stopping you from using that, use whatever you feel like you can play your best in.
