So today I add a PS3 only cthulhu chip to my X360 TE stick. I used a solderless method as the cthulhu has screw terminals, and I was able to use cat5 cable to tap the U,D,L,R and ground via the white plug on the PCB. Info was found here
When I use the cthulhu on the PC or the PS3 everything works fine, but I noticed when plugging it into the PC and going to the controller calibration, if I hold any 3 buttons down on the controller and push the joystick in any diagonal direction, it basically shows ALL the buttons being pressed. The stick only works on the DP mode not the LS or RS, when plugged into the pc. When I use it on the 360, the same thing happens , if i hold any 3 buttons down, and hold a diagonal, it brings up the menu, almost like its hitting all buttons, and the start/back button is getting triggered.
I’m really at a loss at this point, and have spent all day with it, so I’m hoping someone here has some ideas. one last thing to note, I am using a totally different usb cable for the cthulhu so I have one for that, and the original for the xbox.
Thanks in advance for the help.
