The official Cthulhu and ChImp thread - Try our new Dreamcast flavor!

its not my stick but yeah it uses the original madcatz usb cord. i just desoldered the green and white wires from the cord and added new wires to madcatz pcb and cthulhu to connect to the opposite ends of that switch you see on the bottom. from there you take the green and white wires from the usb cable and solder to the center connections of the switch and you have a ps3/360 stick that works through one cable. move the switch left for ps3 and right for 360.

if you do this kind of mod you don’t need to buy another usb cable, you just use the existing one on the 360 pcb.

the cthulhu is really good for this type of mod because it has solder points on it specifically for this type of function.

everybody should buy 10 of them. :looney:

If you have the time, could you go into a bit more detail on how you did that? I’m still trying to decide if I should get the 360 tournament fight stick and dual mod it with the cthulu but for someone with absolutely no experience with any of this, I dont to mess the thing up.

Sick clean work. That’s some OCD level organization there. Great job.

basically what you are doing is piggybacking the cthulhu pcb to the 360 pcb inside the tournament fight stick. there are solder points on the cthulhu that will match on the fight stick. you will want to somehow wire all corresponding input points together. from there you will want to add a dpdt switch to the body of the stick and then wire the data lines from each pcb to the switch to move back and forth for use with either ps3 or 360.

until we see the pcb for the fight stick we won’t know where to map those points to or how easy/accessible they will be.

another alternative would be to somehow wire the inputs of the cthulhu to the fight stick and then use a usb hub but i’ve never tried that method with any other common ground type stick.

until people get their hands on the upcoming sf4 sticks nobody will really know how to dual mod them but so far from what i’ve seen it should be fairly easy for someone to figure it out.

Great job. Thats exactly what I wanted to do too, and what Toodles recommended. Your picture illustrated it nicely. I’ll be sure to get started now. :stuck_out_tongue:

dumb question, but is there a “best” sort of USB cable to use with the board? I hear about usb lag and don’t want any with my stick. Wouldn’t any usb 2.0 cable be good enough?

I’ve never seen a single USB cable that didn’t work beautifully. I suggest you find one that is long enough for your comfort and colored to match your box. There is NO concern about lag dealing with cable length.

This really bugs me. The Start+Select design flaw. Is there a way the Cthulhu can be updated so that Select negates the Start button and vice versa triggering the Home command?

Did you get one that always has start+select activating Home? If so, I can easily reprogram the chip if you can get it to me. If you don’t want to go without the stick, paypal me a $10 deposit, I’ll mail a chip out to you and refund the $10 when I get the old one back. Sound fair?

will the cthulu board work with mame? I just built a stick out of the cthulu board, and though windows recognizes the joystick, I can’t get it to work in mame!

I’m having the same predicament as well. I have no clue on how to do any of this stuff, but I want a dual modded TE stick…

It would be nice if I could send it to someone and have them do it for me, but that sounds kind of risky.

It works just fine with everything, including mame. You need to tell your flavor of mame that there is a joystick; by default it doesn’t use any joystick. Check the configuration of your frontend or use the -joystick command line switch.

actually i found it! yeah, by default, the joystick is disabled! I actually didn’t connect a LOT of the buttons… like 4p and 4k… and home. But overall, it works perfectly! I can’t wait for the universal one!

No, I believe my board is working as intended. START+SELECT will only trigger HOME if HOME is wired to GROUND. The design flaw is that when using START+SELECT method to trigger HOME, I will always get START+SELECT+HOME. It is of inconvenience to me because I have a pretty basic stick and it lacks an extra button that can be used for HOME/GUIDE.

I’ve dual modded my stick with a Madcatz and problems arise when I try to use the START+SELECT method to trigger GUIDE on the 360. It appears that GUIDE will pop up once as soon as you plug in the controller but it acts as if you are holding GUIDE down. After that, GUIDE can no longer be triggered but START and BACK/SELECT are functioning normally.

i was looking to make a stick to play sf4 on pc, but id play it to participate on some tourneys, and most of them will be running on xbox 360. Will I definitively to need to build 2 sticks, one for the 360 tourneys and the other for my trainning on the pc/ ps3 based tourneys? The import taxes are a bit prohibitives in brazil, plus that id like to play the tourneys with the very same gears im trainning whit :frowning:

Sorry i didnt ready the entire thread, maybe someone already asked something like, but im really short on time now, tnks.

That is no design flaw; that’s exactly how it is supposed to work.

Ah. It sounds like you have the guide button connected to the Cthulhu’s Home button. It also sounds like you have Home disabled either by using a wire shorting it to ground or by soldering the Home_Disable jumper which connects it to ground. So your 360 Guide signal is connected to the Cthulhu Home signal which is connected to ground. So, it will always appear pressed to the 360 pad.

I’m sorry you’re under the impression that would work, but I’ve tried to be clear that it won’t. If you’re dual’ing it with a 360 pad, get a dedicated button for Guide/Home.

Just got my box in so I am trying to put everything together.

Does anyone know which wires are what on a 32-01? I think black is ground, but it is in the middle of the wires which seems weird. No idea about what each of the other wires are. Does it matter which spot they are put into (ex. red has to go to down …)?

thanks

The regular seimitsu harness uses the same colors as the sanwa harness, but in a different order. If the pins on your stick are pointing down, then I suggest you check out this picture of sait0u’s stick. If its points elsewhere, you should be able to figure it out.

I have the wires coming out at the top right. I can still follow his wiring though right? It won’t change or anything…?

Thanks for the quick reply.

Yes, it will change. What is up on his may be right on yours, all depending on how it’s oriented.

Grab the orange wire, screw it down on GND. put the other four in whatever direction screw terminal you like. Test it, write down what each direction registers as. Unplug it, and put the wires in the right order based on what you wrote down. If pressing Up showed up as left, then you know the wire currently going into Left should be going into the Up terminal.
