o…k… seems like i’ve got no response yet for my problem

here it is again:

i AM testing my dual modded TE stick on my PC ( i do not have a xbox to test it on)

when i plug it in under xbox mode, no game controller is detected.
the xbox guide button keeps flashing from 1>2>3>4, instead of a steady light on 1.

HELP~~

Either one of your wires has come loose or something is touching something that it shouldn’t. Remove the PCBs and inspect your connections visually. If that fails, Toodles would probably want you to break out the multimeter and start checking stuff.

mR_CaESaR · August 31, 2009, 5:22pm

exactly like what bomberman said.

Here’s what i do when i have issues… I posted this on bomberman’s thread, hopefully it can help you as well

mR_CaESaR:

First question, do you have a multimeter?

If not, go buy a cheap one that can check for continuity, it’ll be the best tool a modder can get (I simply cannot recommend enough learning how to use a multimeter just to check for continuity)

If you don’t know how to use a multimeter to check for continuity, here’s a great tutorial that i used (given from toodles) and as a result, now, I can’t go without my multimeter when doing any form of modding.

Here’s my basic trouble shooting guide, when one board fails to load or no boards load (basically go down the imp’s 7 points you solder to):

[LIST]
[] Ensure the three boards are grounded. Do this by, having one probe on the ground point of the imp and use the other probe and touch the ground of the cthuhlu, then a ground on the madcatz, if you get a successful beep, then proceed to the next step if not, resolder your grounds.
[] Ensure the three boards are powered. Do this by, having one probe on the vcc point of the imp and use the other probe and touch the vcc of the cthuhlu, then the +5v on the madcatz, if you get a successful beep, then proceed to the next step if not, resolder your power points.
[/LIST]

Most of the time, that’s all thats necessary, however there’ll be your odd occasion when you get the “unrecognised usb device” chances are you’ve switched around your data points, placing the - in the + or vice versa. If that’s the case do the following:

[LIST]
[]Ensure the #2 + wire goes to the + wire on the second PCB that you want “activated”. Do this by, having one probe on the #2 + point of the imp and use the other probe and touch the + point of the second PCB you want activated, if you get a successful beep, then proceed to the next step if not, resolder your points.
[]Ensure the #2 - wire goes to the - wire on the second PCB that you want “activated”. Do this by, having one probe on the #2 - point of the imp and use the other probe and touch the - point of the second PCB you want activated, if you get a successful beep, then proceed to the next step if not, resolder your points.
[]Ensure the #1 + wire goes to the + wire on the first PCB that you want “activated”. Do this by, having one probe on the #1 + point of the imp and use the other probe and touch the + point of the first PCB you want activated, if you get a successful beep, then proceed to the next step if not, resolder your points.
[]Ensure the #1 - wire goes to the - wire on the first PCB that you want “activated”. Do this by, having one probe on the #1 - point of the imp and use the other probe and touch the - point of the first PCB you want activated, if you get a successful beep, then proceed to the next step if not, resolder your points.
[/LIST]

If those are all okay, and in you’re case the cthuhlu still won’t activate, then you will need to look at the way you’ve wired up the “guide” point on the imp

[LIST]
[*]Ensure the guide wire goes the point where its going to “switch” the pcbs (ie. bomberman has two versions of doing this, the original version was through the guide button, the new version is through the RS swtich). If you do the guide button way, make sure there’s continutity between the imp guide and the madcatz guide. Do this by, having one probe on the guide point of the imp and use the other probe and touch the guide of the Madcatz pcb, if you get a successful beep then you should have proper continuity, if not, resolder your guide point. If you’re doing it with the RS method, do the same thing as above, but make sure you’re soldering to the correct point.
[/LIST]

If all the above steps have been taken and none of your boards are loading, then check the USB connection on the IMP itself.

The above steps is the steps i’ve taken to troubleshoot ALL of my mods, and never have i needed to go beyond that, i’ve been able to see where i’ve gone wrong and points that “look” properly connected doesn’t necessarily mean there’s continuity through them.

What I highly recommend is checking for continuity between ALL boards and ALL solder points BEFORE installing the USB cable on the IMP. This way you know that all boards are connected properly and SHOULD work once you connect the USB cable.

That being said, if it still doesn’t work, then it’s beyond my scope and one of the more electric guru’s might be able to help you out.

I hope this little trouble shooting guide can help other people that has problems with this mod, I can safely say that I’m now approaching my 12th dual mod and I’ve learned a few things a long the way

Hi guys I am new here.
I have a TE for Xbox 360 and I am sick to beg for ps3 sticks when I go to tournaments.
So I want to make my TE dualmod, have anybody done that with Cthulhu?
I was think about buying a Assembled Cthulhu so I wont have to solder it.(I dont have any soldering skills) .
Plz guys I need help I dont have money to buy another stick.hehhe.
and one more thing after i install the cthulhu is there any lag?

Any idea if this allows it to work on Dreamcast with a PS1 connection via the Innovation converter? Mine doesn’t seem to work with it right now, though it works fine on a PS1 or PS2 system…

Toodles · August 31, 2009, 8:37pm

The core PSX code hasn’t changed, so if it didn’t work with your converter before, it most likely wont with the 1.3 version.
Is anyone with one of the Innovations that doesn’t work willing to loan it to see if I can get it going?

drunkninja42 · August 31, 2009, 8:40pm

I won’t be using mine for a while, so I’d be happy to send it your way if you need it.

System_1 · August 31, 2009, 10:31pm

exactly, i have already examined the connections visually, nothing seems loose.

i am ready with the multimeter if u would just tell me what to check, Toodles

Jack_Steve · August 31, 2009, 10:38pm

Shan - what happens when plugged in for PS3 mode? Do all the buttons and everything work?

Kreeeee · August 31, 2009, 11:14pm

Stupid question time:

If I want to dual mod a 360 TE stick, can I just wire a Cthulhu directly to the buttons/stick and have 2 USB ports, one for PS3 and one for 360, without ever soldering to the 360 TE’s PCB?

I just want to avoid messing around with imps and soldering to the TE’s PCB, and as I understand it I can use Start+Select on the Cthulhu for the guide on the PS3?

System_1 · September 1, 2009, 1:04am

is there any way to install an assembled Cthulhu in the TE
without soldering at all?
if there is plz let me know and step by step =)

thx

System_1 · September 1, 2009, 1:26am

yep, it works fine in ps3 mode.

Jack_Steve · September 1, 2009, 3:28am

I would double check your D+ and D- connections for the Xbox pbc. Maybe you crossed em on the imp board, shorted em somewhere, didn’t solder to the joint well, etc.

System_1 · September 1, 2009, 8:25am

how can i check where exactly is the problem? based on visual examination, i dont see anything wrong.

can you point me in the right direction, Toodles, as to where to check voltages/resistance to pin down the source of the problem?

hehehehe
I will do it myself…

manman · September 1, 2009, 11:03pm

haha, cool…yeah, I don’t think there’s any way to install it without soldering… you can cut down the amount of soldering you need to do by using the screw terminals, but you’ll still have a good amount of soldering to do on top of that…

Truckasaurus · September 1, 2009, 11:46pm

I’m down for some loanage too if you need another one
