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

I was about to ask that actually. It didn’t make sense that you could leave the pots on…unless they’re set perfectly in the center since the center pin will be reading whatever voltage the INV pins are giving it.

Waiting on a buddy to get the rest of his parts so I can dual mod his stick, can’t wait to test drive the ChImp!

I just tried it out on my xbox. Same thing happened. If I hold down start+select when I plug in the stick, the guide button is pressed, but pressing them again won’t cause guide to press again.

works for ps3/pc though

Do any of the resellers happen to sell the Cthulhu to MC upgrade kit or can that only be ordered directly?

Well, Im looking through the code and the best guess I have so far is that the line is staying is still reading a low voltage for a short time after the pin has gone from output to high impedence. Chip sees the low voltage on the line, and thinks there is a legit Guide button.

I’ll have to look into how to fix it, but this is the exact sort of thing I wanted the beta for.

There’s never been a high enough demand for the resellers to want to bother, so for the time being, they’d have to come from me.

Just placed an order for one, thank you!

Hmmm… perhaps I’m getting confused with the technical terminology, but if a PCB can be hacked using a single ground point in a system using a daisy chain network (as well as linking this single ground point to other common ground PCBs), does that not make it common ground?

Here’s a pic of a simple mod (DC ASCII FT edition) I made for a customer last year. Apologies for the poor quality image:

It’s only of a single PCB setup, but I should have some of dual PCB setups (360 +DC, 360 + PSX) laying around somewhere. If not, then I’ll just make another myself and post up the results :slight_smile:

In the pic above, GND is tapped from ‘button A’, but can also be tapped from a few other locations. Unlike the wired Mad Catz 360 pads which are not common ground but have a few buttons in common line, all the buttons and stick directions on these MS pads can operate through this single ground point.

Bomberman - what sort of issues have you heard can happen using MS wired pads in CG configuration? Curious as I haven’t come across any issues yet, but if there’s something I should be looking out for…

Great, thanks for the response. One last question regarding this so I don’t have to clog up your inbox - would I be able to get Cthulhu’s, MC Cthulhu’s, and IMP’s from you directly in kit form? If so, I’m looking to place quite a large order with you for approx 20 boards.

Thanks,

:sweat:

That pcb has a common line, agreed. But that common line is not ground.

Please, but please post up about it in a different thread.

FAQs, first post.

Then does there not seem to be room for a further calssification of PCBs?

[LIST]
[*]Those that are common line, but where all buttons + directions can be tapped from a single ground point (certain MS models)

[*]Those that are common line, but where only some buttons can be tapped from a single ground point (certain Mad Catz models)
[/LIST]

Again, sorry if I’m confusing the issue here. However from what I’ve learned from personal experience, the MS wired pad models (as I’ve pictured above) can be used in common ground configurations (and CG configs with other CG PCBs) by accessing just a single ground point.

So how does that make these MS PCBs different from common ground PCBs if they can still be implemented in dual mods in exactly the same way? Granted, the GND tap point has to be specifically placed instead of just anywhere, but it’s still just one GND point you’re tapping.

Is there going to be a way for us to update the pic like we do for the mc cthulhu? Not that I need the start+select=guide functionality for 360, but if you make changes to the code, how will we be able to test it? Will that be something that’s up to the next batch of beta testers?

Okay, so here’s an update on my situation. When LuckyDay asked me to take a pic of the back of the 360 pcb I unscrewed the screws that were holding it down. When I was putting it back the way it was the screws weren’t going in all that smooth so I left some room between the wood and the pcb. And voila! When I went to test it out again on my 360 I was using, it crapped out on me and red-ringed. :frowning: So I hook up another 360 that my son has with my harddrive attached and the controller doesn’t do the pause thing I was having issues with on the other system. Now my last question on this subject (hopefully), is it possible that the wire(s) on the back of the pcb were being smashed and for some reason when I hit all 6 buttons it would pause? BTW, SF on the PS3 works fine also.

You are confusing the ‘common’ and the ‘ground’ parts; they are two entirely separate animals.
Oddball ( usually ‘matrixed’) pads - there is no single line that is common to all directions and buttons. Nothing general about these can be stated because many act in very different ways.
Common line - there is a single line that is common to all directions and buttons.
Common ground - a common line pcb, where the common line is connected ground (0 volts).

Please, this discussion has nothing to do with the Cthulhu. If you need further clarification, take it to a different thread, either the stickied newbie thread, the padhacking thread, or the ‘2 pcbs in one stick’ thread.

There’s no ability to update the firmware on the chimps. I’ll be making some changes to see if I can fix that problem with the start+select to go out with the rest of the chimps I have here.

Well not having the start+select thing isn’t a problem for me so I guess its no big deal.

Is there any other functions of the chimp that you need tested or to look out for? It seems everything is working fine except the start+select thing. I’ll continue to test out both sticks on as many systems possible.

Hey Spektrum, if you’ll cover shipping ($6), I’ll send out a replacement chimp chip for your two button stick; if the code tweaks I put in work, you’ll have the start+select thing working better on 360 and wont need guide wired to select (and I’ll have a good test of the code changes). Interested?

Hey toodles

Sorry,

Is it still possible to pick up a MC Cthulhu and chimp board?

Yup. Everything you need to order is listed in the first post.

Doesn’t work on the PC unless PC mode is the same as 360 mode even though it shows up as a Chimp device and the buttons need to be remapped.

Holy run on sentence, batman! I have no idea what you’re trying to tell me.

lol when the chimp is connected to a PC in force 360 mode, it still shows up as a Chimp device. The buttons are also mapped differently than what a 360 device would have.

You’re holding down light kick, medium punch, and hard kick, and waiting a couple of seconds after unplugging it before plugging it back in that way, and it still shows up as a chimp?

Yep, I assume A, Y, RT are the appropriate button combinations. It auto detects just perfectly on the ps360.
