Wow... That UMK3 board is gorgeous and high class.

So that’s why they call it a “kick harness”. Honestly... never knew that was the significance. You learn something every day.

I watch every one of your videos and I will probably never own an arcade cabinet. It’s pretty fascinating getting a glimpse inside the hobby though. Again, nice production quality and good content.

I did similar about 20 years ago, when developing a swappable fighting stick build. I'm glad to see my idea wasn't as convoluted as people thought.

As an new owner of MK1 board, I will definitely do this so I can swap it into my SF2 cabinet, thanks!

Thank you. Toying with the idea of a candy cab one day. This makes sense for multiple hardware.

I came to a similar solution for my hori arcade stick - I wired it up with a db15 so I could plug it into my supergun/mvs, but then I wanted to also use it on other systems, and didn't want to unplug every pin from the buttons each time I switch systems. I've used the cheap ebay db15 breakout boxes for now, there's no soldering and they have a plastic case, but they are on the large side. db9 would be good too but I needed more pins.

What an elegant solution. Well done!

"I was fooling around in the basement........" Heh

Hell I'd be happy with stereo connector standardization.

Awesome fix. I wish I had a cab to play all the old arcade games.

Yea, this looks like a perfect solution to the issue of kick harness swap outs. Clean, nest and easy... Well, easy once pinned out... Haha! Thanks for the tip!

Lotta hot button shots here. I stopped watching Kenneth Copeland tongues remixes to come here and I was not disappointed.

I know this first world problem all too well. My solution was to standardize on one format across all of my boards for the games which require a kick harness. The standard I went with is CPS2 style connector. The way I did this is via CPS2 harness adapters for everything I own, including MK2, UMK3, CPS1, Namco System 12 (Tekken Tag 1), Sega ST-V and Taito F3. I thought about doing something like this re: DB9 connector but I decided I really didn't want to touch my cabinet wiring at all when I change boards, which is frequently. Now all of my cabs are wired "permanently" with a CPS2 kick harness and all of my boards connect cleanly, as if I was swapping a CPS2 motherboard. Even Atomiswave was adapted to this standard, via Atlus adapter at the JAMMA edge which moves buttons 4 & 5 to a CPS2 style connector. Everything I used to make this happen was purchased from JNX or from the user community on the A-P forums. Now if you want to talk blasphemy, I play MK2 and UMK3 on an Astro City cabinet. But at least I do have the option of plugging in a USB controller/stick for those games, which was another thing I did to those machines.

I have a JVS setup in my net city and I use the jammafier from irken labs, its a pretty damn good piece of kit for jamma to JVS without the headaches!

Somethings the small stuff is the most interesting out of them all Scarlet. Nice work for sure. Amazing that you did this bro. 8^) Anthony..

Love the UMK3 PCB! Looks amazing. I love JNX so many hours saved in mvs consolation/kick harness standardization

This was a great explanation. For those that don’t want to solder to the DB9 connector, you can buy male to female cables and cut them in the middle, then connect the wires to the wires on the PCB specific connectors.

both of us? dude. awesome video. thanks.

Thx for diving into this. Interesting to know. I was mulling over starting an arcade collection the same time I was researching a JAMMA set up to consolize the MVS. Glad I gave it up and just decided to go the MiSTer route, but I'm still an arcade fanboy. Noticed you have AvP running on your Astro City cab. Holy grail game for me. Played the hell out of it in college and MAME later

I did this to my cabs because I had a mess of 3 spliced harnesses in each cab. Tekken mk and sf. It was when I got the small cab super gun that had db15 for controllers and db9 for extra buttons that I thought to standardise my cabs. Was going to wire my splice all my arcade standard jamma to db15 too but haven’t got around to it.

Those sketches are actually hi res graphics :) For me i just have one jamma cab (new astro city) so i crimped all my kick harnesses (namco, midway, capcom) to the 10 pin amp connector. Complications arise when you throw jvs into the mix though! Eg. sega rev b jamma to jvs which assumes buttons 1-5 on jamma, and button 6-9 (yes 9!) on kick harness, necessitating another harness which connects between control panel and control panel headers. Crazy, but i guess i enjoy using all the original harnesses.

Street figther has kick pin battery. As far as rewire you can also use (2) 8 pin molex connectors well 1 male a d 2 female use mk board female 8 pin molex and leave kick mk plug with mk board and leave kick street figther plug with cps2 a board male 8 pin molex connector stays on jamma harness in cab. Is how I used to do them makes easy in a d out no matter board

Funny you're using this in an astro city I thought all already had this setup included from factory. In mine the kick harness has two AMP female connector on each end, one in the panel next to the 1 and 2 players usual plugs and one inside the cab where you can then change the end of the cable like you did. But good trick ! well done

Interesting video! But perhaps you can put for db9 connector an hood plastic and no hot glue? 🙂 (or this installation is for test in one step) Jamma nation help me several times for finding solution about modding... last time, for change battery on a slot with not rechargeable battery (and pull off some composant for no charging)... happy they are here for helping hand (and other one 🙂) It’s cool to see your basement again!

Man, bless that button check in the UMK3 service menu, right? :D

good info...

Nice

How does that apply to my street fighter II CE that I have running with a supergun and Saturn controllers? How do I plug/wire the kick harness in this case?

Hello, I’m thinking about getting an apricade to put into my total carnage cabinet with a jamma harness. Would the four joysticks work with a jamma harness?

Dude help me out here. I'm looking to buy an Ultimate Mortal Kombat 3 pcb. Is it just one main board with integrated sound or is there a separate sound board? I see a few on ebay but listed as just mainboard

Some call it art 🖼😜👌

Man. I'm kinda pissed that the Jamma standard COULD have supported 6 buttons (instead of giving us unused pins and some duplicate Grounds). UGH!

Shit this is brilliant!!!

This is the #1 thing preventing me from being a true arcade fan. I have 40-some PCBs, but still don't have a box of random wires and connectors for projects like this. For shame.

Unrelated question do you have a ki 1 . Reason I ask is I been looking for a ki 1 that its Toshiba laptop hard drive did not warp and throw errors due to heat in atract mode. I do know you can get a micro sd solution but want a original setup

🖐 I watched to the end. Have you had a chance to put any time into MK3?

Could you not purchase a female CPS2 connector and then build a CPS2 to Midway adapter? Then you wouldn’t be “inventing” a new standard with DB9 that you’ll need to remember when you build another adapter

Next livestream soon?

lol, both of us...
