Killer Instinct 2 machine is done… for now

So I finally “finished” my killer instinct 2 arcade machine de-conversion.

Here are the changes I’ve made since the last update…

1. Tuned the monitor. The convergence on the monitor was way out of whack because the yoke was lose (missing a few wedges) I replaced the wedges aligned the monitor and build some homemade convergence strips to improve the image. I couldn’t get the convergence perfect but it’s better than it was and everything is secured properly now so it wont be falling out of adjustment again. I also manually degaussed the monitor because it needed it badly.

2. Added a light shield above the monitor glass, it bugged me that the marquee light was leaking into the monitor glass, a small strip of poster-board and some staples fixed that easily.

3. Repaired some of the structural wood that was lose, this picture is of the monitor bezel and glass support, it was coming lose and twisting so I pulled it, put fresh nails in it one size larger and then glued it in place. Now the bezel even lines up with the monitor better than it did before.

4. Kick panel fill, smooth and wrap. I glued wooden dowels into the holes left from a lock bar, then I bondoed them smooth and filled some rough edges along the bottom. Sanded that and the black portion of the sides smooth. Once everything was dry and smooth I wrapped it in Matte-Black 3M Di-Noc Vinyl (the same stuff they use to wrap cars).

5. Coin doors were powder coated, all the parts cleaned and rebuilt, even put some fresh bulbs and new locks in there.

6. Touched up paint on the control panel box and some scuffs in the side art.

for reference here is what it looks like before the touch up paint:

7. All new fresh T-Molding

There are a few things that still need to be done but I can’t do them until I find the parts…

  1. I need a coin door blank to fill in the bill validator slot
  2. I need a control panel overlay to replace the matte black placeholder I have there now
  3. I need a midway 120mm fan mount for the cooling fan
  4. Not needed but I’d like new graphics for the control panel box front and sides

Sadly none of those parts are readily available so I’ll simply have to keep an eye out and buy them if and when I see them pop up for sale.

Killer Instinct 2 Deconversion

Last month I cam across an eBay auction for a former Killer Instinct 2 arcade machine.  I say “former” because this poor machine was converted to “Turkey Hunter USA”. A conversion generally means spray-painting all of the original cabinet artwork black, replacing the computer board and the marque and finally gutting the old control panel, covering over the original control panel art with new art and drilling fresh holes for the new controls. It’s quite sad to see, and it’s something I hated doing when I worked in an arcade.

Killer Instinct 2 is my all-time favorite arcade game, they’re pretty uncommon to find in arcades these days and they’re fairly uncommon among collectors as well and growing in value.  The cabinet for sale had the turkey hunter controls and PCB removed so it was just a cabinet and monitor with Turkey hunter art work. $200 +another $150 or so for freight shipping. I decided to buy it and this is what I got:

machine_01 machine_02

I had a lot of parts to order, I had to buy buttons and joy sticks, a Killer Instinct Marquee, new control panel lexan overlay and art, and the condition of the monitor and power supply were completely unknown and of course I had to buy a Killer Instinct 2 PCB, without that it’s just a fancy box. Lots of other little things such hardware, wiring, connectors, etc.

Paint Removal/Cabinet:
First thing was getting the paint removed off the original artwork, this was first because I wanted to get it done out in the garage before moving the machine indoors. I first tried a product called Lift-Off, which worked but not very well, I then switched to a different product called Citri-Strip, which was fantastic. The results:

I also attempted to remove the Turkey hunter control panel graphics, after unbolting the plastic overlay I tried both a heat gun and goo-gone to separate the new control panel art from the original control panel art, the results, sadly, weren’t that great:

You can see that the new art work pulled up some of the paint from the original art, leaving nasty white lines of missing graphics. Even if that wasn’t the case there were three additional holes drilled in the original overlay around the player 2 joystick and the colors were all faded and dingy (the Killer Instinct logo on the Control panel top is supposed to be red just like the Killer Instinct logo on the control panel front).

I managed to find a new, never used Killer Instinct 2 marquee, which made for the easiest and best looking part of the cabinet “deconversion” so far.

Of course even this took some work, the marquee was for a conversion kit (meaning for people who wanted convert a non Killer Instinct machine to Killer Instinct 2) so it needed to be trimmed to size.

Electronics:
The power supply was making some horrid noises, it wasn’t even the original power supply. I pulled it and bench tested it and found that the output voltages were way off so it was getting junked. The monitor was making some horrible noises too, the PCB I put int to test it wouldn’t boot (due to the bad power supply) so I couldn’t determine if it worked or not.

For some odd reason there were hundreds of finishing nails among other bits of hardware on the floor so I cleaned all of that up to prevent any electrical shorts and I bought a new power supply, then modified it to fit in the original mounting location (the junk one that came with the cabinet wasn’t original and had just been screwed into the floor)

This let me boot it up but sadly the monitor wasn’t showing a clear image

I pulled the monitor chassis and bought all new capacitors and a new flyback, I also planned to replace a few small parts related to image sync  to fix the horizontal sync issue the monitor seems to be having. Here is the chassis with all of the new parts installed:

No good, after reinstalling the image quality was better but the monitor couldn’t hold a sync; it was even worse than before. After getting advice from a few experts they told me to check that I hadn’t installed one of the new parts backwards… after pulling the board back out again and checking I found that the part in question wasn’t in backwards but the solder joint wasn’t strong enough, fixing that, and reinstalling the board I get a nice stable picture. Some small adjustments still need to be made but on a whole the picture looks great.

Control Panel:
Not only was the original control panel gutted and then drilled out when it was converted but all of the original control panel wiring had been cut out of the machine as well. I had to completely disassemble the control panel and install new tee-nuts for the joysticks. I bought all new buttons, joysticks and switches. I couldn’t find a Killer Instinct 2 control panel harness for sale so I would have to build one. I found a harness for a different Midway game that used the same style connectors and wiring colors so I bought it. Repinned the connectors for Killer Instinct and then routed, trimmed, and crimped a disconnect onto each wire. Here is what I started with (just 2 wires!), and what I built:

Control Panel Overlay and Monitor Bezel:
I still haven’t been able to find new control panel art, so I made myself an temporary cover-up out of some black poster board. I also bought a reproduction laser-cut lexan control panel overlay and I had new monitor bezel stickers printed from some scans that I found online.

The Results so far:
So I’ve got all of the electronics fixed and rebuilt the cabinet has been washed clean of all the Turkey Hunter conversion stink, the last bit is to plug in the Killer Instinct 2 PCB I bought and fire it up:

I got a few games in and I’m really happy to have all the work so far pay off.

What’s left to do:
I’ve still got some finishing touches to do here is the list

  • touch up paint on the side art to cover up scuffs and scrapes
  • repaint the front lower section of the cabinet
  • replace a coin door light bulb
  • find and install a bill collector blank for the hole in the coin door
  • find and install a proper control panel graphic
  • properly mount the KI2 PCB
  • install a cooling fan for the PCB
  • fine-tune the convergence on the monitor
  • built a light shield to prevent the marquee light from bleeding onto the monitor bezel
  • install new t-molding

I’ll get some of the larger items on this list done soon, but other items might take a while to source the right parts. I’ll do an in-depth wrap up video once I’m 100% done.

Arcade Control Panel

So recently it was announced that they’re releasing a Tournament Edition of the new Mortal Kombat game due out next year.

As a long time Mortal Kombat fan this is obviously something I’m excited for, I’m even more excited since it’s an all new developer making the game and they seem to be making it a true sequel to the original 2D trilogy as opposed to continuing with the 3D mess that the MK series had become.

The Tournament Edition has me really excited because, well it’s a CE, which I love, but it’s also going to be limited to only 20,000 copies. The biggest thing about this CE is that it includes a Joystick as the main bonus item.  I’m making this post because it seems that a lot of people fail to realize how much of the “real deal” this included joystick is.  Allow me to demonstrate.

Here is a photograph showing the joystick included with the Tournament Edition:

Take a close look at the controls, that is a Happ Ultimate Joystick and Happ arcade buttons with Cherry micro-switches. I worked in arcade repair for several years, nearly ever arcade machine from the 2D Mortal Kombat era uses these joysticks and these buttons…

Need further proof? Take a look at these pictures:

That is an actual Ultimate Mortal Kombat 3 arcade control panel, it’s a conversion machine but those are the buttons and sticks included with the kit from Midway. I wired this control panel myself, and this machine is sitting in my game room, and those are two Happ Ultimate joysticks and Happ buttons with cherry microswitches way back from 1995.
