I recently got one of these sticks off a friend for cheap, but the ‘fierce punch’ or yellow Y button is, well, busted. Otherwise the stick works great for things like Ikaruga and I like it a lot, hell I wouldn’t have a problem with that button being busted if SFIV wasn’t right around the corner.
The problem specifically is that, say I went under ‘game controllers’ in Windows and held down the button, the input would flicker on and off. In actual gameplay it seems to work about 50% of the time. I haven’t done tons of research but this doesn’t sound like a problem with the PCB but rather the button itself.
I’d like to fix it but I am incredibly cheap (read: poor college student) and am pretty awful with a soldering iron so I want to keep the whole modding thing to a minimum. I see guides recommending Sanwa OBSF-30 buttons, but I’ve been told that Seimitsu PS-15 30mm buttons fit better. I’m assuming that I’d be using wires to connect it back to the PCB so I guess the length doesn’t matter?
Also, I read one post from someone with a similar problem saying that simply desoldering/resoldering the button could fix the issue. I’m not really sure how or why this would work but it’s worth a try, I guess.
