According to your post, the voltage on the VCC screw terminal when plugged in was below 2 volts. You then unplugged everything from the board and tested the resistance between the VCC and GND screw terminal, and showed a resistance far less than 1k ohms. That’s a short. If you assembled the board yourself, you need to hunt down the short and fix it. If you bought it preassembled, you should check with the folks who sold it to you to see about a replacement.

I already mentioned you where the one who assembled it. -_-

Sweet Zombie Jesus! Yes it is a PSX/PS3/360 mod with an MC Cthulhu/IMP, thank you for clarifying the VCC flow, now the stick is running smoothly. I have a triple header cable PSX/GC/Xbox that I want to solder on another cthulhu, but when I do that, all the spots on the V column become filled, where would I connect the IMP VCC to the Cthulhu then, with all 3 consoles installed? Could I splice it in with one of the console VCC’s? Or is that a bad ideal?

Thank you again :love:

USB cable power -> Imp
Imp VCC wire-> one of the V columns on the Cthulhu (doesnt matter which)
PSX VCC wire -> a different V column (preferably rows 1 or 2)
(one of either the VCC screw terminal or unlabelled point A) -> 360 VCC

Great, what’s your zip code?

Uhh, how close of a look at those cables have you done? They’ll only take up two spots in V column if its the same as the ones I have done.

Got my kit yesterday. Finished soldering up today. Will test it in a few days after i buy the rest of the stuff. Thanks Toodles!

[Truckasaurus]

My fault, I didn’t clarify, this a different, brand new setup. I’ve got 3 system cables installed with a triple header cable soldered onto the Cthulhu, GC/PSX/Xbox. So the entire V column is occupied with all 3 systems, GC/PSX/Xbox1, I don’t know where to put the VCC coming from the IMP onto the Cthulhu board. Tried soldering VCC IMP together with one of the VCC’s already occupied on the V column, also tried going from VCC IMP to the USB VCC on the IMP, but no attempts were successful.

Where does/can the VCC IMP onto the cthulhu when the entire V column is occupied with Gamcube/Playstation/Xbox system cables?

Try VCC screw terminal on Cthulhu to VCC IMP. I don’t think that’s the safest route but it should work.

The best would be to have it go to the USB VCC. If you’re board was a kit, solder the VCC wire from the Imp to the hole labelled ‘Red-V’. If you have an assembled board, well, hmm. Either solder a wire to the pin underneath the board, cut open a USB cable and solder the wire wire to the Imp VCC pin, or grab an extra diode from somewhere and connect it to the VCC screw terminal.

[Truckasaurus]

I don’t think that’s a good place to put it. I Had it there initially and that screwed everything up. If I follow the USB pathway that Toodles explained to me, it has to be soldered somewhere at the “head” of the board where the Multiple Consoles and the USB jack go in order to pass thru the diodes, and the screw terminal VCC is reserved for other PCB VCC’s like a 360.

I’m just going off experience, and the setup your recommending is one of the initial ones I did with no success. Perhaps something else is wrong, and you could be right and Sweet Zombie Jesus knows I’ve been wrong before. I Appreciate your chiming in to help me out though

Please help me!!

Can anyone lend a hand in guiding me to a online site that actually stocks
MC Cthulhu pcb’s (Multiconsole). ???

I cant seem to email Lizard Licks…( and it also appears they only stock the standard pcb’s anyway),

Modchipman appears not to have any either.

Are these pcb’s like sold out??.. some help in this matter would be so greatly appreciated : ) i am a noob after all. :sad:

Wanna make 3 sticks and post them online once done.

I’m a massive fan of 2D fighters. And if can get set up will try and host Casual play groups in QLD, Australia.

Anything to keep the scene alive! :lol:

[B.A.L]

I’m just gonna ask again. Is there a how-to on how to dual mod an Xbox 360 TE with the assembled Cthulu board? Would be really helpful

Bomberman’s guide should tell you everything you need, and a number of folks have done the mod with assembled boards. Check there if you have any questions.

Toodles, I don’t suppose you feel like linking to my guide in the first post?

Dual Mod w/ Madcatz Arcade GameStick (4758)

I’m not sure if it has been posted before, but I had to learn this the hard way…

I just finished a dual mod with the Madcatz GameStick (Part number: 4758).

There are 2 cables coming out (1 for xbox360<USB>, 1 for Cthulhu MC <PSX>). I made 2 PSX converter cables. PSX->USB (PS3) & PSX->GameCube (Wii). The wiring is all correct, but I was getting some “latching” on a couple of inputs.

On xbox360 the Rth and Lth were “latching” on any input even on directions.
This happens on the Cthulhu MC (PS3) for the “Home” and “Start” buttons.

After trouble shooting the problem went away by connecting the VCC’s from both PCB’s to each other. I wanted to avoid having both PCB’s powered up, but this was how I got rid of the “latching” problem.

I hope this helps…

Hey Toodles, I just would like to thank you for creating the Cthulhu board as easy as it came out. I purchased one recent from LL and just finished soldering it together within about 30 minutes.

Never soldered before, but I took an old tv pcb and practice soldering a few times before touching the Cthulhu and it turned out to be far simpler as it seemed.

You’ll be looking at another custom stick baring you’re Cthulhu spawn ^^.

I just got a random question though, when you hook the pcb to a PC, what do the button 11 and 12 (in Game controler control panel of a PC machine) represent exactly?

I didnt have my full stick up so I wired 1 button and went down the line of buttons to test if they all worked and I never really saw button 11 and 12 light up. I’ve gone through Home/Start/Select/1-2-3-4 P and K, up down left right and they all lit up in terms of 8 3 2 6 4 1 9 10 7 13 5 (off the bat of my head) but not 11 and 12

[Toodles]

Hehe. FAQs are in the first post, including that question Glad you like it.

[TheZen]

Oh wow, silly me. I just remember reading that a few weeks ago before I bought the pcb XD Guess I’m high on arcade stick mania

[Truckasaurus]

I had initially figured that “RED VCC” would be the best place to put it, and when I tried it out, everything was still acting funny. After much frustration, I just switched out the cthulhu with another brand new cthulhu and still had problems. So I switched out the triple header cable I was trying to use and just put in a single PSX cable to make sure it wasn’t the board, and when I did that, everything was working fine, so it was the cable that screwed everything up. This “Arsenal Triple Header Extension Cable” was what I was trying to use and solder to the cthulhu, but it caused me so many problems and a lot of second guessing myself and was the bane of my existence for the past week and a half or so. I cracked it open to look inside it and here is the shitty solder job hiding inside the cable that is probably why it made everything act all fucked

Here’s some knowledge I want to impart to others:

1. DO NOT BUY THIS TRIPLE HEADER CABLE!
2. Soldering IMP VCC -> RED VCC (where the USB jack would go) is the best place to put the IMP VCC if the V column is filled with all 3 cables GC/PSX/Xbox1
3. Check the installed extenstion cables for an MC Cthulhu if things aren’t working but the wiring/cthulhu are fine
4. Ride the Walrus

Thanks again for the help

Sounds like you’re pulling too much current. I don’t know exactly how you have things wired up, but move the incoming USB power line from the USB cable or the Imp to one of the V columns using the black diode (column V, row 1 or 2). Also doublecheck the PSX VCC is also going through the other black diode. (The glass diodes are rated for about 100mA before problems; p360’s pull in the area of 60 or more milliamps by themselves. The black diodes are rated for a full amp, 1,000 mA, if I recall right). Also make certain the p360 and xbox360 pad are both powered from either the VCC screw terminal and/or the unlabelled VCC hole.

Hi Toodles,

It worked like a charm! I owe you one. Thank you for the support and the great product.

**Just a heads up people

If you are piggybacking a 360 pcb with trigger mods, you will NEED to go the hex inverter route. The reason being is because the transistor route still carries an active analog signal (hot) over to the cthulhu which is no good for the ps3 interface along with any other ones you have connected. the button stays active no matter what when you switch over to ps2/3/gc/xbox**
