can someone link me to toodle’s solderless dual PCB guide? i have a 360 TE stick and a cthulhu. it doesn’t seem to be in his cthulhu thread’s OP.
I searched through the thread and it looks like if I wanted to dual pcb an hrap3, i could just solder a wire to the vcc and one to the ground on the hrap3 pcb and then solder the signal wires from the 360 pcb to the quick disconnect signal wires. which looks easy enough but is there an easy solder point for the home button so I can hook it up to the xbox guide button?
if i wanted to install an imp then i’d have to find a way to get at the usb signal wires right? Can someone point me to a diagram of the hrap3 pcb?
When dual modding PCBs that require resistors for the analog triggers (eg. Mad Catz classic arcade and gamepad), is there any extra step that needs to be done or can the triggers be connected normally to the other PCB that doesn’t require resistors?
Up until now, i’ve always dual modded without regards to analog triggers since I never had a use for them. But now I’m wiring them up so I can always have access to them if I ever need them.
There’s no easy way to get to home signal; you’ll have to follow the trace somewhere accessible like a via and solder a fine wire there.
If they just require a pull up resistor, you’re fine; just connect everything up. If the triggers need to be inverted like the newer Madcatz pads, use an inverter chip and resistors instead of the transistor and resistor method. As long as you do that, they’ll go together just fine.
I just want to ensure I have this correct before getting to deep into this. My plan is to link a MC Cthulhu board (PCB1) and a madkatz controller (PCB 2) together allowing it to be used on a ps3 and 360. So if Im correct in the diagram, I need to get a terminal strip, link the Cthuhlu to it, then link the same cords from the 360 controller (orange to orange, brown to brown) into the same port on one side of the terminal strip. Also Id need to solder the grounds’ from the boards together (the 360 and Cthulhu) and their power voltage ports? Then link the other side of the terminal strip to the respective parts on the buttons/joystick? Also the picture only depicts 6 buttons. Where do you link the start/select/home button? Also will cable for both the 360 and ps3 come out of the MC Cthuhlu as I believe you have to cut the cable for the 360 board? Thanks and sorry if it makes no sense, I have no experience with PCB’s or soldering.
So I’ve done maybe 8-10 dual stick mods no problem, however one I’m playing with now has a bizarre issue: The kicks don’t work. Only in game.
Stick is a 360 TE, which is a pretty easy dual mod. I soldered it all up as usually, plugged it in and everything seemed to work. I was navigating menus, home button worked, and then I loaded up SFIV. I jumped in to training mode and tested punches, all okay. Then I hit kicks. Nothing. No input detected. I was confused, as I had to hit “A” (LK) to select menu items and it worked. I hit start, went to button config, and made sure it was on default (hitting A to select stuff) then i went back to test again but I got nothing. It’s just bizarre because I’ve replaced the Cthulu, all of the wiring (right now it’s not even connected to the Cthulu at all) and I still get nothing from the kicks… only in game. The buttons work fine for everything else (navigating menu, etc).
The same applies to ps3 when I did have the Cthulu hooked up. X and O worked fine for menu navigation, but would not work in game.
Any ideas?
toodles has told other people with this problem to try turning off the triggers in the controller config, it should work then. he said that they messed up the triggers on the 360, give it a shot.
Sounds like a ‘KKK button is always pressed’ problem.
But did you turn on input display to see what was being pressed? I wonder if all three kicks would show for every frame.
You’ve done enough of these that you’re skipping checks for mistakes. After the problem was identified, the first place you should have gone to check is the game controller applet in control panel, to see what if any buttons were misbehaving in either Cthulhu mode and/or 360 mode.
Verify that one of the buttons is always being held down. Find the misbehaving short or bad button, and fix it.
Thanks Milkham and Toodles. I guess I’ve gotten a bit complacent and overconfident in my skills. Apparently a small bit of solder somehow managed to get on the side of one of those little square bits next to the bottom of the pin next to LT. I couldn’t see it and I had to take a good close hard look to find it. It was in no way obviously unless you really got in there with a magnifying glass.
I’m not sure how it got there, it was barely big enough to see. I’ll have to take more care in the future.
For those who have done a HRAP3 + Xbox360 mod, which point on the HRAP3 pcb did you use for HOME/GUIDE? I read a few posts about soldering to a point on the bottom side, but I can’t seem to figure out where I should solder to.
Here’s pics of the top and bottom sides (not my pics - they’re from another post on srk):

Hi. I’m dual modding a Hrap 2 and a Mad Catz 4716 controller. I’m having quite a few issues but the first thing I’d like to know is where is the 5v on the HRAP 2?
i would like to know this as well, i’ve been searching for a while but found nothing
Just an observation. I’ve noticed that everywhere I look there are only diagrams of sticks and not arcade stick PCB’s. I’d really like to know where the 5V and ground cords are on the HRAP 2 cord.
This is such a great thread!
I need to know whats the simplest way to dual mod a PS3 and xbox360?
I don’t mind having to cables coming out of my joystick.
can i just do the dual pcb method by connecting the grounds and 5 & 3.3 volts to both pcbs?
or are there any problems i may encounter?
I will be attempting to do a Dual PCB mod on the HRAP 3 using a Madcatz 360 wired controller. I’m in the process of getting my materials together; just gotta get the stick and open it up to see what im working with. I hope it goes well…
Hey guys.
Has anyone here tried to dual mod a modded mayflash?
I have one and i’m going to add a xbox wired (non common ground) pcb on it.
Any tips?
I was wondering about the joystick, because, the mayflash’s joystick is wired directly in the mayflash’s little PCB through some little slots.
So, if i’m going to add a xbox pcb, i’m gonna have to use a wire harness right?
I had to cut the traces of the JLF’s PCB, would that be a problem?
Thank you.
Wii Fighting Stick?
Hey folks. After my last stick went so well, I figured it might be a good birthday present to a friend to build him a multi-PCB stick. I went ahead and bought a Hori Fighting Stick Wii, reading that it was common ground and figuring it’d be the cheapest base to build a multi-PCB stick off of.
After cracking it open, I noticed that there’s 2x solder points for every button right on the back of the board. (As well as 2 for every direction) This normally wouldn’t be a problem, so remembering the whole ‘common ground’ thing, I tried seeing which points were the ground by comparing them to each other with a multimeter. Only problem is that said idea isn’t working, and i’m not able to figure out which are which. (I’m noticing what I think are resistors along the paths between the different buttons) In either case, none of the points at all seem linked, be it by GND or anything.
Oh, and obligatory crappy mspaint picture to help give image:

Should it be helpful, I can take a photo of the full board and post that as well.
Anyway, I figure this one really won’t be too hard at all. (Just soldering wires to the existing solder points) I just need to first know which point (for each button) is the +V and which is ground. Anyone have any ideas or suggestions?
Thanks for your time.
EDIT –
Nevermind, hadn’t realized at first I could see which points tie to the black chip at the top of the PCB. I’m guessing as well that since the grounds should all be connected, i can just solder the common ground on the PSX PCB to any of those points. Yes? No?
everything i’ve read says you can’t dual pcb with a non common ground pad?
From what I understand you -can-, but you really really really don’t want to. Getting a common ground pad makes the solution a lot nicer to deal with. (Toodles can better explain why you -don’t- want non-common ground. )
Crap… 
So, i’ll have to make another stick.
I still want the explanation about why i can’t do it without a common ground please.
