i used bombermans first post and this picture:

i have it switched to RS when i plug it in and it wont show up as an the madcatz stick but only as the cthulu…
i will try to rewire it today as Kakitajamie said and post my progress
Good man! Now make sure there is no continuity between VCC, GND, D+ and D- (any pair of those touching==no workie), and also verify the voltage on the USBVCC point on the TE to make certain it has power.
No continuity between any of those, but resistance is only .38 kOhm between USB 5V and GND. Does this imply a short? I’m baffled as to where I could have shorted something on this board, and how I wouldn’t be able to tell on the Cthulhu (since they share solder points for all buttons). Voltage between USB5V (I assume this is what you mean by USBVCC?) and GND shows 5 Volts.
Has anyone tried to install a retro PCB into a PS3 SE? My googles have failed me and I didn’t wanna open mine yet cuz it’s still new without confirmation, so I’m not sure how much vertical clearance I’ll have to put it somewhere.
retro PCB?
Yeah, sorry, the madcatz retro arcade stick PCB, it’s a decent sized square. Seen here: http://www.joystickvault.com/showphoto.php?photo=2149&si=Real
The resistance sounds way low, but not rediculously so.
Hmm, I just checked one of the 360 TE’s I have here, and the resistance is showing as way higher than that; its a slow climb because of the capacitors, but I stopped measuring when it hit 130k ohms. There shouldn’t be that low of a resistance.
Doublecheck the orientation of the resistor arrays on the Cthulhu, and also use the multimeter to measure that same resistance with various buttons and directions pressed.
Also post up:
did you buy assembled or kit?
does the board have diodes on it?
where does the power line from the TE connect to?
what are you using to control the Imp? (guide, RS switch, etc.)
are you using either of the solder jumpers on the two boards? (the DISABLE_HOME jumper, the USB_ONLY jumper, and/or the unlabelled jumper on the bottom of the Imp)
Elementator that subject is off-topic, but I think it’s physically possible.
Ah, sorry about that, didn’t think about it enough.
But thanks, I think I might as well give it a go.
I rechecked the USB5v -> GND resistance with a friend to look at the meter (so I could concentrate on getting good contact) and we got readings much much higher. I think that was just my personal error earlier.
Just checked the resistor networks again, and they’re in just like the Instructable says. I assume that the Cthulhu is assembled correctly as it works right.
I really hope I’m just retarded and forgot a jumper or something, it would make fixing the stick a lot easier 
Thanks a bunch for responding, Toodles. Hopefully we can figure it out.
Is your Imp assembled correctly?
I went through Toodles’ diagnostic and have found the Imp to be performing the switching correctly. Is there an incorrect configuration that would allow 2D to work but not 1D?
a lil help
Okay so I installed MC cthulhu and imp in an 360 SF4 TE stick.
That went well… er so I thought until I plug it in.
When I plug it into the PS3 the guide button lights up but nothing happens.
Same for the 360?
Is there something I missed?:xeye:
^ go through the troubleshooting guide linked above your post. That will either help you fix it, or allow you to ask a more specific question about your problem.
I am looking for the most up to date proven diagram for a 360 TE, MC Chutchlu, IMP with the MC set as primary.
I found allot on here, but they were all up for debate, which diagram was settled on?
I’ve done 3 using faux’s diagram as a visual base and Bomberman’s literature for step by step (an explanation for what & why I’m doing). Even though 2 of the ones I did were using Madcatz pads not TE/SE PCBs, it all works the same. I also use the piggyback points on the Cthulhu, way easier than it looks…
Just curious. Why does this diagram have the purple Ground connecting all 3 together, then it has a black Ground connecting the Cthulhu with the 360 PCB, and then it has another black Ground connecting the Cthulhu with the Imp? Can’t you just do one or the other? Or is there a reason why you need to do both?
The purple G is GUIDE.
I’m dumb. :china:
Here is a dumb question: on all these diagrams it shows you which solder point goes to what button, but there is never a line going from the one to other.
Do they just not draw that cause it would get to cluttered? Or do you not have to wire each button? Like does up on the chutchlu have to have a wire going to up on the TE board?
