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

Asking questions in the noob thread: brilliant. Thank you for doing that.
Not reading the noob thread first, well, it is kind of large but very recommended before undertaking your first project.
Not searching the noob thread first? That’s just silly. Just searching the ‘absolute noob’ thread for ‘wire’ brings up the question asked and answered. Multiple times.

But posting in here because your posted question wasn’t answered within 30 minutes? Your answer is in the noob thread ready to be read at your leisure.

EDIT: went out of line, I apologize.

[Taiki]

If you would read back a page or two you will find your answer.

reading fail. thanks Kaytrim!

I know this is a totally uneducated guess, but could it be a problem delivering enough juice to the madcatz pad? I thought that maybe the with the ASCII optical in my stick needing 5v as well as the it might be just slightly underdelivering the needed power for both.

Nah. Figure your stick might be pulling 60mA, that’d leave 20mA each for the pcbs which should be plenty. The USB ports have to be able to provide that without complaint or they lose their USB logo certification. I’m sorry man, I seriously have no idea how that problem could be troubleshot down further and fixed as locked up as those pads are.

No need to apologize at all. Thanks for the ideas to figure out this bug.

Any idea as to why the security chip might suicide? Is there such a thing as to a company using cheap chips?

I would expect that the security chip death is a suicide similar to the how CPS2/3 systems have a suicide, but not battery related of course. The little microcontrollers they use for the security chip can cracked in a manner of speaking with the right equipment to get the hex code from the chip and allow anyone to make their own peripherals without a Microsoft tax. This is something they want to avoid, so they may have put in some conditions to kill itself if it thinks it is being attacked. I don’t think it’s a matter of chip failure, but the only way I could know would be to try and reprogram the chips to see if they still work. That would be a lot of work just to determine if its accidental or by design, and wouldn’t help fix the problem even if we knew because I still wouldn’t have the original code.

Just wondering if anyone has an idea: will it be pretty easy to Dual PCB a SFIV TE stick with one of these and have everything run through one USB cord?

Show me a picture of a SFIV TE PCB and I’ll tell you. :arazz:

We won’t know for sure until it comes out, but it should be doable, and according to MarkMan, it should be easy. I’ll try to have instructions on how to do it up as soon as possible, but unless MarkMan wants to be my Secret Santa this year, that will have to wait until after the thing is actually released.

Awesome. Thanks.

Hey Toodles, I see that people have connected a 360 pcb to the Cthulhu in order to make themselves a combo stick. Would this be possible with the Wii as well?

[Toodles]

Everyone, it’s finals time of year and I’m getting assraped pretty bad by classes. LizardLick will be taking care of orders as usual, but I just won’t be available for much for at least a week from today. If you have something you absolutely need me to look at, please send me a PM on Wednesday and I’ll get to it asap, but I just won’t be able to do jack shit except school until then.

Hey Toodles, I see that people have connected a 360 pcb to the Cthulhu in order to make themselves a combo stick. Would this be possible with the Wii as well?

With a wii-mote? I don’t know. It should be possible to do with a classic controller, and definitely possible with a gamecube controller.

Good to know, thanks Toodles!

Hey guys, I did some searching but couldn’t find a specific answer. I’m going to be mounting the Cthulhu onto MDF. Can I mount it directly onto the MDF or should I use a spacer? I see a few people used spacers form the pics in the first post, but I can’t tell if some are mounted directly to the case.

I forgot to order mounting screws/spacers when I ordered the board, so I’m hoping someone local will have them. Maybe I can use some that are made for a PC motherboard.

Thanks!

MDF is not conductive, so you can mount it however you like, including right up against the wall of the stick. I’d suggest starting with #4 (best) or #6 wood screws.

With wiring the buttons, I need to have a ground to each, correct?

Yup. Each button will have two wires to it, one going whatever button you want it to be, and the other wire going to one of the ground screw terminals on the board.

I’ve seen the term daisy chaining them tossed about on the board, but have not found a proper article on how to do this. It’s like putting the grounds together somehow, right? How does one go about doing this?

Slagcoin’s site will probably explain it better than I can.

I’m guessing that I should have one daisy chain for the face buttons and another for the Start/Select/Home since a Cthulhu has 4 grounds anyway, and then I’d have 3 being used as 1 is for the stick?

Sounds like you have the idea right. Having one for the stick, one chain for the face buttons and one for the control buttons would probably be the cleanest way to do it, and is how I do it on the few I’ve worked on.

I have wire cutters/crimpers/splicers already, and some 20 gauge, as well as those red ended QDs from LL, so I’ve got all I need now, finally - save the knowledge of how to wire, correct?

Sounds like you have it all covered, yes. Good luck, and definitely post up pics!

Hey, I sent you another PM. I’d like to know as soon as possible, because during break I’m planning on putting a 360 pad into my HRAP2 and I’d like to know if I should wait for the Cthulu or not. Thanks

[System_1]

Toodles,
I know your busy with finals and all…
I’m trying to use the Cthulhu to port a PS2 Guitar Freaks controller to PS3.
The original controller has both dpad left and dpad right engaged which is how the game recognizes it. I’ve tested the cthulhu with a windows driver, and if both buttons are pressed it only shows left as being active. Is the chip programmed to disallow this possibility? If so, can it be reprogrammed?

Thanks.

[Toodles]

If that’s the only way it can be detected, then, no, I can’t reprogram it to be able to do that. The two ways the Cthulhu directions are reported are with a POV hat switch, and an analog X/Y; there is no way to make either of those report two directions at the same time.

i mounted mine directly to the mdf with wood screws. you’ll be fine

i thought about hot glue, but didn’t want something so permanent.

Hope your on winter break. Keep us updated on the progression of the multi-system Cthulhu.
