An update is coming soon that will address the different steps in using a Cthulhu or MC Cthulhu and an SE or TE PCB.
Also I finally added the step about jumpering the # 1 diode spot in PS3-only Cthulhu setups to the guide.
when i plug in my stick in 360 mode the turbo leds flash red once and then nothing happens.
Ps3 mode still works fine.
Is my SE’s PCB dead?
No, it’s just some wiring mistake. Hopefully Faux or Toodles can talk you through it.
oh thats good, thanks!
if your turbo LED flashes, then you’ve definitely got a wiring problem, its the home/guide button that should flash when you plug in the cable…
good luck.
oh thanks! I’ll go take another look at it. Funny tho, my guide button works fine in PS3 mode.
quick question, i want to make the RS switch on my 360 SE the system changer into ps3 mode. Default will be 360. So do i just wire the RS signal from the SE to imp? And then wire the SE guide to the ps3 guide to make the ps3 guide function through the button? thanks
Exactly correct.
thanks toodles it worked, finally finished dual modding my 360 SE. Works great!
Sooo close to completion but I think I’ve taken some steps backward.
A) Sometimes when I plug in the cthulhu board to the PC it registers as the Virtua High Grade stick.
B) I’ve had problems with the buttons registering as pressed when they’re not. This is usually two buttons together and when I try to resolder it I get no luck. I don’t see any solder connected, could it be something I’ve done to the SE board?
All boards must be powered.
Thanks I found this very helpful.
Bomberman, is the part that goes around the additional system cables, Neutrik NE8MC-B-1, required? Or is it possible to just use the RJ-45 connector alone without breaking the small tab?
Good question, Soarer. I’ll try to remember to test that when I get home. But if you’re using a Neutrik jack then you really should go with Neutrik connectors too. Otherwise it would be cheaper to install a different kind of jack. Many of us favor the Neutrik products because they will last far longer than regular RJ-45 connectors, which can easily break after prolonged use.
Oh boy, so apparently I didn’t look twice and I purchased a fully assembled MC cthulhu.
Did I mess up and should I get this thing swapped? Or can I still use this? For some reason I thought this might make it easier to work with, but suddenly I feel like I may have messed up somehow.
There are two points where the USB port is that apparently I have to solder to according to Bomberman’s guide.
Should I keep using this chip?

I haven’t started any work on it yet, and am wondering if I should bother with it now before I get myself into trouble. Apparently this makes it so I don’t have to solder onto this, does that mean I can “wedge” wire into the adapter area and not have to solder to the Cthulhu if I’m using this? It sounds awfully neat if this is the case.
You don’t have to get a new one, yo!
edit: but yes, that’s how the screw terminals work.
you coud probably solder the D+ and D- lines from underneath, I had an assembled Cthulhu and tried to remove thos screw terminals and they pretty much screwed up the connections and broke a resistor network, so now I have to use the 2 top rows. Thanks to toodles I managed to salvage the cthulhu though.
couldnt you use points D and E instead?
An assembled Cthulhu works just as well. When connecting the signal lines between the Cthulhu and the 360 pcb, you have your choice of either soldering those lines to the unlabelled holes on the end, or just screwing the wire down in the screw terminals; your choice, it makes no difference electronically.
For running the wires to the Imp or DPDT, you can solder a wire to the D and E columns for the D+ and D- (which is which is listed in the faq’s in the first post of the cthulhu thread).
Sounds good, so it looks like I’ll be fine then.
So you’re saying instead of running wires to where they normally go, to solder a point to D and E gor D+ and D- respectively?
Basically from red, to blue arrows?

And yes, I am a complete noob at this and most likely fail but I have a lot of heart. :3
PS: Bomberman, my SE has adapters on it where the joystick connects to on top of other things. I leave those alone I gather, plugged in and resting “underneath” the pcb once mounted?
