Brook Universal Fighting Board into a Hori SCV stick. Help appreciated

Tech Talk
1

I recently picked up the version of the Brook Universal Fighting Board with all soldered headers (thanks, Paradise Arcade Shop). While I’m decent with wire strippers and a crimp tool, my soldering skills are surely not up to snuff. I’d like to avoid soldering if at all possible…

Here are the button functions that I’d really like to retain that are part of the sub pcb on the top button panel:

  • PS
  • Select
  • L3
  • R3

The following are nice-to-haves but really are not a priority:

  • Port LEDs (1-4)

The rest I don’t care about at all (don’t use ‘em)

  • Turbo
  • Turbo LED
  • Toggle switches

I’ve done my best to trace what’s what on the sub and main pcbs. Take a look and let me know if my guesses are correct.

Sub PCB

Main PCB

Now I see only one ground wire and one VCC wire on the sub pcb (well…at least feeding the right ribbon cable).

But the Brook Universal Fighting Board manual states that I’ll need the following:

  1. Dedicated Ground for Start/Select/PS
  2. Dedicated Ground L3/R3
  3. Dedicated VCC for Port LEDs

I could most likely daisy chain a ground wire feeding from the Start button (off in the corner of the case). If that’s the case, I could then use the ribbon cable Ground wire (for L3/R3) and VCC wire (for the Port LEDs)…right?

This is making my head hurt, so thanks in advance for your input.

Ask in the sticky thread.

Done.

hey, how’d that all workout for you? i’m about to do a similar mod to my SCV, but i plan on using the switches (using a hori FC4)

It worked great actually! Everything but (of course) the toggles, turbo and turbo led functions worked well on my PS3 and PC. Auto detect had it up as an Xbox One controller on my PC, but I had no real functional problems.

Note though that player LEDs did not respond on PC unless I had the stick registered as an Xbox 360 (hold 3P at USB connect).

I ended up giving the SCV to a good friend of mine (excuse to get him back into fighting games…to the dismay of his wife, ha).

Now going to put a UFB in the new SFxT VS stick I just picked up :slight_smile:

can you show a picture of all the connections you made thank you

7

I’m sorry, but I let that stick go a long time ago. Sadly, I didn’t take photos of the finished installation.

8

i just wanted to know if the sub pcb was right

9

the wires itself was right because i cant get the ps and select to work

10

I’d say check your connections for Start and Select on the UFB. If the other buttons on the Turbo panel work, then the GND connection is good. That one GND serves the entire sub/Turbo board. Check the signal connections.

11

I’m trying to attempt the same mod on the 360 version of this stick right now. Everything works except for my top panel. I went off your wiring, but I think the 360 might differ slightly.

12

Pics of your boards would help to confirm.

13

I sort of brute forced my way through the problem lol. I am now getting inputs from the home button but they aren’t consistent. Still no inputs from select. I’m assuming it’s an issue with the connections. Did the smaller wire from the sub PCB give you any trouble with connections?

14

Nope, though I cut and re-crimped to appropriate DuPont connectors on the 20-pin. Check the ground. Brute force means what exactly? Pics (again) would help

15

I went wire by wire until I was able to receive input. I’ll try to get some pics when I wake up. I wasn’t sure how to get the board off of the top panel when I first looked at it lol.

16

You have to unscrew all the front panel (using Hex Keys, a little bit larger than typical madcatz TE 2009/2010) to have access to the turbo board

17

Finally got pics of the top panel PCB. Looks identical to the PS3’s to me.

Edit: I think I figured it out. My major oversight was not realizing that the 360 stick has player leds around the home button while the PS3 version has them to the side. I think this determined how they wired it. Thanks for the help guys.

Another edit: Got a better picture.

Final edit: I got all my essential buttons working now. I can finally upgrade my firmware and use it on other consoles :).
