This is my first custom built arcade stick that will be multi-console. It’s still under construction as I still haven’t have my box finished yet but the internals been put together and tested.
NOTE: UDATE the MC Cthulhu firmware before soldering the Imp v2 to it or you’ll have problems!
Wiring diagram hope this helps a bit (corrected)

Let’s start with the PCBs. Here I’ve got the MC Cthulhu and Imp v2

I’ve soldered the RJ45 pin connector to the Imp v2

For those who dont want to solder a RJ45 pin connector this is a diagram of the board for direct wire solder. I borrowed the pic of the Imp v2 from LizardLicks photo since I dont have one without the pin connector and photoshopped each spot.


Here I soldered the wires on the underside of the MC Cthulhu row 1 G,A,B,C,D,E,F,V and one wire to the 2nd row V

I then soldered the corresponding wires to the Imp v2

I’ve also soldered a wire to the VCC point on the Imp v2 and connected the other end to the VCC screw terminal on the MC Cthulhu

Then I prepped the Madcatz Xbox 360 PCB that I took out of a Brawl pad.
I cut the USB cable at a decent length so I could just use the wires off that to solder instead of soldering new wires.

Now soldering the xbox PCB to the MC Cthulhu. I soldered all the corresponding wires to row A-H and 1-9.

http://tapatalk.com/mu/ad319e4f-e672-e83a.jpg
I’ve put everything together to test out if everything is working and it’s working on PC/360/PS3 so far with no problems. I haven’t made the other cables yet.

I promise it won’t look so messy like that once it’s in the box lol.

Hot glued the 360 PCB wires
