So this is the mayflash usb fighting stick. the pcb inside is compatible with ps2/ps3/pc (xp and vista). the stock parts are pretty crap. the stick is really loose and unresponsive, and the buttons are plunger style buttons that miss inputs real easy if your pushing buttons real fast.
this is what you've got on the inside. you'll want to remove the 4 screw that hold the stick down, then unscrew the balltop to get the stock stick out. the red wires are ground (it's a common ground pcb) so you can snip them off altogther. cut off the black wires as close to the stick as possible so you can use them later. (edit: this isn't always the case with the wires. i've seen sticks where the colors were mixed up, so check with a multimeter to figure out which 4 are ground.) then unscrew the black plastic plate that holds the button pcb down.
the button pcb needs to come out. you can desolder it where the pins meet the main pcb, but it's easier to just bend the pcb up and break the prongs off. now remove the stock buttons and the pcb.
you'll need to file out the button holes from 28mm to 30mm. first thing you'll want to do is file down the tabs in each hole (pic above has 5 of the tabs already filed down). then file out the holes to the proper size. keep a button on hand for test fitting purposes. if you have a dremel and a griniding bit this will go much fatser.
after dremaling. not a huge difference.
so that's the underside of the pcb. just above the "clear" button you'll see 9 small soldering pads. these would be buttons 1-8 and then ground. it's a pretty tight space, but you'll need to solder wires to those tabs.
done!
back to the inside of the stick. to mount the jlf i put a cutting wheel in my dremel and cut off the little tabs the stock stick screwed into, and part of the plastic wall that surrounded the stock stick. this will allow you to undermount the jlf right up against the plastic. you'll also want to use the jlf mounting plate to help you line up your screw holes. those little black marks in the above pic are where i drilled. now it's time to mount the parts.
i decided to remove the top sticker and paint the whole case. 2 coats of plastic primer and a coat of textured gray. i'm a total novice at painting, but it came out pretty good.
as far as parts, i used a sanwa jlf with a violet seimitsu bubble-top, sanwa obsn-30's (violet) and sanwa button plugs.
a messy wiring shot. wiring is fairly simple though. 5 lines for your stick including ground, and 6 wires for the face buttons.
the finished stick. altogether, this is a fairly easy mod, so long as you have some experience in soldering. if you have any questions, i'll try to answer as best i can.
