Here's my current setup:
 

 
Killer Instinct 2 currently has a Raspberry Pi3 B in there with a pi2jamma interfacing with the cabinet. So it's a MAME cabinet right now. I can put it back to stock very easily though once I fix my KI2 board. I also have KI1, MK1, and MK2 that are all working and plug/play easily into it.
 
Maximum Force cabinet was a pretty big project. I have an 8 way JAMMA switcher in there and there are 7 boards inside of the cabinet. I built "shelves" to mount them all to inside of the cabinet. The 8th slot is external and I have a longer cable running on top of the Rush 2049 SE cabinet right next to it, so I can swap games on the 8th slot without having to go inside the cabinet and open it up. I have like 15 or 16 light gun games now I think.
 
Then both Rush 2049 SE cabinets are just 100% stock and linked together.
 
I don't really have more room down there or else I'd probably get a trackball cabinet.

Let's see some love for the cabinet owners in here.
 
Here's my latest Chewlix. Picked up locally
 

Oh hai there. New cabs!
 
 
Two Sammy Atomiswave cabs with Third Strike included set up for head to head already. Just acquired yesterday.

Forward: So yes I straight up stole a guide that I didn't write. I will leave a link here to the original thread

This guide also applies to the PS360 Plus,  the Brooks Retro Board and various other boards that use RJ45 system cables.

Hopefully if SRK ever goes down again we have an archive of this valuable guide

(Note from OP), This first post is all about installing RJ45 cables to the MC Cthulhu and installing a RJ45 jack to your stick.
Skip to the second post to see the cable pinouts 

Intro

This post is a rewrite of Acceptable Risk?s RJ-45 Tutorial. This was posted to include new info such as recent console support added because the pinouts are spread out in the Cthulhu thread. Also I instead uses a Pass through over a keystone punch down type jack.
The MC Cthulhu is a purpose built PCB for hooking up with arcade joystick components. To work with different consoles, you only need to solder wires from a controller extension cable to the appropriate spots. If you look at the top op the pcb there are 3 rows of solder points with columns labled “GABCDEFV”. Each extension cable wire must be soldered on to the appropriate column. When plugged in, the MC Cthulhu PCB can autodectect what system it is plugged into and then make your joystick work for that supported system. Be sure to download the latest firmware to ensure that all of the console cables you make will be compatible.
 
Originally the MC Cthulhu was able to support 5 consoles using 3 cables, therefore only 3 rows, but now it has grown to include many systems. Because there are 8 columns for system cables a Ethernet jack was a natural fit. The connecter used is typically an RJ-45. If you want to do a dual mod with Xbox 360 pad then you should check out this tutorial. https://forums.shoryuken.com/t/rj-45-mc-cthulhu-imp-xbox-360-dual-mod-tutorial-diagram/92427

Kitty info Update: If you dual modded your stick with a Kitty board, they come preinstalled with a RJ-45 jack. If you connect that to a RJ-45 pass through, then you can use the same cable pinouts for making your own custom cable.

Supplies List:
 

(OP) Original Tutorial Parts 1 and 2, relevant for the MC Cthulhu, but not for system cable making. 
 

Here's some stuff I've made over the past year or two:
 

T6 Wireless for 360.  Sanwa silent buttons + custom stick with levered switches/octogate. Xbox button swapped out from a 360 controller. 
 

Another T6 wireless.  Converted to Brook Universal PCB with Neutrik cable plug.  Custom stick with levered switches/octogate, turbo switch for use with shmups.
 

AFS shell, Korean stick modded with Cherry switches.  Buttons are MX Browns.  Brook wireless board with Adafruit 2500mah battery.
 

Battery kill switch to manually turn off the board, custom USB type-A cable port, custom wireless LED/antenna mount.

Even though I'm awful at it, I've always like Virtua Fighter. So it's not the multiple options that turn me off from Tekken. I don't find it engaging. It's like Monster Hunter to me. I see what other people like, but it's not my cup of tea. Speaking of  which, I wish Sega would get off their asses and make VF6 already.

That is another really good point.
 
I don't know if its the player base, placebo, or what, but I definitely feel like the overall connection quality of SFV has gotten worse over time. 
 
My tinfoil hat theory in general is that CFN adds some level of overhead that made the experience worse after the beta (no accounting for it feeling a little worse  over time though). I always felt like the CoD games got more jittery as they layered on more stat tracking and shit like that so in my crazy little corner of the world SFV may be suffering from the same thing (especially since Capcom seems low tier overall with their netcode).

That's because FBA has input lag and can sometimes have weird framerate problems.
 
If you have to emulate then MAME is a better experience, but then of course you won't be able to play with anyone online.

I'll wait for Falke but if she does little for me I might dive into Alpha 3 once again, my favorite SF game.

Starting to get a bit frustrated with the game. Not sure I want SFV to go beyond season 3 tbh.
