Title: J-Pac with Mame and SF2
Post by: porkins on February 03, 2014, 04:27:10 pm
I am using a J-Pac to connect my Jamma cabinet and extra buttons to a PC through the keyboard connection. Everything works fine, but I was wondering about the response in fighting games like Street Fighter 2. When I try to do moves like throw a fireball as Ryu, it just doesn't work. If I do a half circle, back-to-forward, I can get it to fire off more frequently. It is just not picking up the down, down+right,right inputs like it should. I am wondering if anybody has experienced this kind of issue using a J-Pac. I am thinking it is a limitation of the keyboard input having trouble registering 2 keypresses at the same time, or maybe just not registering quickly enough? I have the competition joysticks. Would a different interface work better? Thanks!

The problem lies not with your interface, it is somewhere else. It is your sticks, your switches, your wires, your mame settings or something else.

if you hook up a SF2 PCB can you throw a fireball?  maybe check the actuator on the bottom of the stick, make sure its in "8 way mode"  :dunno
