Both boards get 5V, haven’t checked D+ on the 360 yet.
I had this issue during testing, make sure when the screen pops up to run Sf4 or do controller settings, that you do controller settings, and map them there first.
If you don’t, some buttons won’t be recognized and some may be backwards.
Mine showed the same symptoms, and I actually desoldered and resoldered points because I thought things were backwards when they actually weren’t, I just didn’t set the controller buttons in the first pop up screen.
D+ on the 360 PCB is 3V above ground.
I’m going to swap the D+/D- wires on the Imp so that the PS3 goes to the 2nd set while the 360 goes to the first set. If the Imp works and the 360 PCB doesn’t, then I should get a USB error when I plug it in without pressing the Guide button, right? If it shows up as a working stick, then the swap function of the Imp is messed up.
For soldering the PS2 cable to the MC, does the official PS2’s cable wire colours match the instructable?
You’re going to have to use a multimeter, the PS2 wiring varies.
Well, shit. I swapped the two data pairs and the Cthulu works fine when the switch is set to DP or LS, but RS doesn’t work (which I assume is now for the 360).
I just discovered that the Guide point on the 360 PCB that goes to Guide on the Imp is shorted to ground somehow. The capacitor (?) right next to it still shows a capacitance that’s the same as the others… All the soldering looks fine. Only thing I can think of is that some solder went underneath the cap and shorted its pads, which I doubt because I flooded it with flux and remelted the pads.
So I disconnected the wire that goes from Imp Guide to Guide on 360 pcb and now all three slide switches (RS/DP/LS) enable the Cthulu.
EDIT: This diagnosing isn’t going so well. Just a minute ago I was measuring a short between ground and all of the inputs, but in the controller options the buttons and stick operated normally (the red circles would light up when you pushed the buttons). Even stranger, just checking the resistance between ground and any given button using my multimeter would make the red circle light up. Now it seems to be working fine (resistance is non-infinite only when the button is pushed and the red circle doesn’t light up when checking resistance). The resistance isn’t 0 when the circuits are closed, though. It’s about 10 ohms.
For some reason my Window XP wouldn’t recognize the MC Cthulhu as a game controller, but instead shows some USB error. What could it be?
It’s wired up wrong.
The MC works perfectly fine on my PS3 and I’ve used my other USB controllers perfectly on the same USB port on the PC, then what could be the explanation?
Edit: Same thing seems to happen to my PS2. I’ve tested the continuity on the soldering and the PS2 pins constantly, and it always matches up but still doesn’t work on PS2. This is using the row 1, ground wire on the G column and whatnot. What gives?
What did you do about Guide? I’ve read that the dual shock analog button is used. Is there a combination to get this button out of the mc cthulhu?
need help I tried ordering one of these pcbs but they are sold out does any one know any other site that might carry some in stock or know when they might become available ,or sign up for email alerts any thing would help thank you
Hey Toodles it’s probably a human error on my side. but i got my board yesterday and wired it up through this morning, It’s powered and works, the joystick inputs from the p360 appear fine and accurate, however I’m having an issue with buttons.
It seems as if I can not hit more than one button at a time (if i try dashing in marvel i get a fierce punch)
And if I hold fierce punch and hit light punch, it will negative edge a fierce punch. Same goes with fierce kick / roundhouse. I’m sure its a wiring problem on my end but I looked at it and rewired it for an hour before i decided to come and ask, any suggestions?
Grab a multimeter and go through the troubleshooting guide linked in the first post.
The PSX support still pretends to be a basic digital only PSX pad; there is no analog button to press. There is only the normal buttons and dpad.
Pull up the control panel applet for the game controllers and verify what is being pressed or released there. Especially check if anything is showing as always pressed.
I did that, the following happens:
If i’m holding fierce or roundhouse and tap punch, punch lights up for a second and fierce blinks out like it’s not being held, then punch dims out and it goes back to fierce being held. No two button presses have happened at the same time in the app.
That’s messed up. Remove all of the wires out of the screw terminals. Keep the USB cable plugged into the cthulhu, and run a wire from the GND screw terminal to the 1P screw terminal. Plug it into the PC, check the properties, and only one button (uh, button #1 I think. Maybe #4) should be steady lit. Unplug from the PC, add a wire from 1P to 2P (so one wire from gnd to 1p, and another from 1p to 2p) Plug it into the PC, check properties, and both #1 and #4 should be steady lit. If that’s the case, then when know the cthulhu can read the buttons fine. Remove the wires, and screw in the wires for ONE button into 1p and ground. Plug in, test, make sure it works fine. Wire in the second button, test. As soon as you get a button that makes it wonky, you have a much better idea where the wiring problem is.
edit: Forget everything I said, I’m a fucking idiot.
I’m having an issue with my PS3 Cthulu. In the XMB, everything works until I press start+select for the home button. That part works fine, but in the menu after that everything stops working. Also, if I don’t use the home button function, everything seems to work fine except quartercircle motions from the right side don’t work. I’m plenty capable of doing a fireball from the right side of the screen, but not with this particular board. Otherwise I can jump, duck, walk forward and back. Once I use the home function though, everything gets turned off. I haven’t tested 2nd player charge motions or anything, but I don’t imagine it matters. Any suggestions?
