Posts having to do with Arcade Machines and Pinball Machines!

Hey there!!!  Another TNA code update is here!  This is a short, but good one.

I have fixed a few bugs and added what I like to call “Speed Runs” to kill each reactor.  What do I mean you ask?  The game now displays reactor uptime on the display telling you exactly how many seconds each reactor has been online for.  The timer starts as soon as the reactor start scoop has been hit and stops when the reactor is destroyed.  These speed times are stored in the high score table as “Reactor X Speed Run Champ”.  There are 10 of these.  One for each reactor and one for Total Annihilation!

Every second counts when battling these reactors so be sure to skip the reactor startup animation and be sure to skip the bonus count at the end of your ball.  Your reactor uptime pauses if another player is up, but the timer does not pause until after the bonus count.

Have fun everyone!

Code Update Procedure:
WARNING: Updating code on your game will reset your audits and settings on the game after the update procedure. However, these audits and settings are automatically dumped to the USB stick as a backup for your reference. I am planning to add functionality to save audits within the game in the future.

Step 1: Download the latest “pkg” file from the link above.
Step 2: Copy the “pkg” file to a USB flash drive. Do not change the name of the file, should be named “tna-gamecode.pkg”.
Step 3: Power off the game and remove the backglass.
Step 4: Insert the USB flash drive into an open USB port on the PC located on the right side within the backbox.
Step 5: Power on the machine, a message should appear saying that the software is updating.
Step 6: Once the code update is complete, remove the USB flash drive and restart the machine.

Hey Everyone, it has been a long time since I did an actual pinball related blog post, so here it is!  I have been getting a ton of questions lately on how to properly power opto transmitter LEDs and how to hook up the receivers to the SW-16 P-ROC boards.  I am going to walk through it in enough detail that you should be able to get up running on the concepts quickly.

Powering Opto Transmitters

Opto transmitters are nothing more than high powered infrared LEDs.  For this guide, I am going to be referring to the Williams/Bally style opto transmitter which can be seen here:  This LED emitter has no circuitry attached to it by default.  These LED emitters are also used on the small PCB and bracket assemblies seen here: and other various trough board assemblies.

In order to safely power this LED, you will need to gather a few data points and make a couple small decisions.  You will need to know the forward voltage of the LED, maximum constant current that the LED can handle, decide what input voltage you would like to supply to it (5v or 12v), and decide how much current you would like to give the LED to ensure it has enough power to transmit infrared light to reach your opto receiver.

So here is our data:

  • Forward Voltage: 1.7v
  • Max Constant Current: 100ma, but I recommend you do not exceed 75ma to maximize the life of the LED.  This will be powerful enough to transmit a pretty decent amount of distance between the emitter and receiver.
  • Input Source Voltage: 5vdc is my recommendation as it is higher than the forward voltage of the LED, and low enough that the resistor does not have to dissipate too much heat.

These LED emitters will need a current limiting resistor in series with them as applying 5v or 12v directly to the LED will cause it to overload and fail.  Now, to calculate this resistor value, we will need to calculate resistance and power based on the data that we have.  Now, I could be idealistic and talk about the actual calculations, but I am going to show you how I usually calculate this using an online LED resistor calculator.  The one that I use the most is the one below.  I have already filled out the fields, but feel free to change some of the values up to see what happens.;VF=1.7;ID=75

So as you can see above, the calculator has automatically figured out what the ohms and recommended resistor wattage should be for our emitter.  What I also like about this calculator is that it gives a nice visual representation of how to wire the circuit and what the resistor color bands are.

Important note: Please be sure to use at least the recommended resistor wattage.  You can see above that the calculator is recommending at least a 1/2 watt resistor.  Too small of a resistor and it can burn up, which is bad.  🙂

That is about it for powering an opto emitter!

Connecting Opto Receivers to the SW-16 P-ROC Board

Now for this section, I am going to be talking about the Williams/Bally style opto receivers and how they hook up to the SW-16 P-ROC switch boards.  These are the black colored opto receivers that can be fond here:  These, just like the emitters, are also used in small PCB assemblies, and trough opto boards as well.

To connect these optos into the SW-16 P-ROC board, you will simply need to wire it directly to the inputs of your switch board.  It is really that easy.  It will act just like a standard switch as long as it is connected in the correct orientation.  Below, you will see an image from the P-ROC documentation.  The cathode/ground side of this diode is the side with the flat indentation on the black epoxy base of the opto.  Please also keep in mind that opto receivers are normally closed switches and when it detects the IR beam from the emitter, it will close.  This is opposite of a normal switch.  When a ball breaks the opto beam it will go from a closed state to an open state.

The full documentation can be found here:

I hope this all makes sense and helps you get your project up and running!  Please also keep in mind that some Stern and certain Williams trough boards have resistors built into them on the emitter side.  The guide above will allow you to connect to boards and directly to emitters that have no circuit logic.

Hey Everyone,

The wait is finally over.  I have finished up version 1.2.0 of the TNA code.  This new code update contains the new co op (all players vs. the machine) and the team vs. co op (players 1 and 3 vs. 2 and 4).  There are also a bunch of other little fixes and additions.  Please see the changelog clip below for more info.

To start a game in co op mode simply hold the start button down for a few seconds when adding player 1.  The game will flash a confirmation on the LCD and a callout saying that co op mode is enabled.  This is standard co op mode, which is all additional players are working together as a team to destroy the 9 reactors.  All scores are shared, no extra balls, replays, or high score tables are enabled.  It is your team vs. the future, that is it.

If you would like to make things a little competitive in co op mode, there is another co op type that can be selected.  This other mode is team versus co op mode.  This mode can be activated by pressing and holding the start button for a few seconds after the standard co op mode is enabled.  This mode requires 4 players and will revert back to standard co op if not enough players are added before shooting the first ball.  In this mode, players 1 and 3 will be going up against players 2 and 4.  This is also called “odds vs evens” in some tournaments.  All progress and scores are shared between each of the players within their respective teams.  Just like standard co op, no extra balls, replays, or high score tables are enabled.

As with any software release, please let us know if there are any show stopper issues on your game.  Please contact and we will get back to you asap.  Thank you and enjoy!

Hey Everyone,

By now you may have seen the post by Spooky Pinball where we revealed the final artwork for Total Nuclear Annihilation.  I am so happy with how this whole thing turned out and the artist, Matt Andrews, captured what I was going for in this game.  Below, you will find the images that Spooky shared along with some other glamour shots not yet seen!  🙂  Enjoy














Hey Everyone,

Last night was awesome! Total Nuclear Annihilation was featured on the Dead Flip Twitch TV stream and we had a blast!  We even showed a glimpse of the beautiful backglass artwork by Matt Andrews.

Here is a recap video of my best game ever on the machine!

Also, for fun, since you guys could not see the backglass very well, below are a couple pictures of parts of the digital copy.  Enjoy!

BG Detail1

Full Backglass:


The version of the backglass shown last night on the Dead Flip stream was a version without cutouts for score displays.  We made this one first in case we could not use these displays in production, but I fully expect them not to be cut out of the production game.

Hope you guys/gals enjoyed!

Hey followers! So a lot has been going on behind the scenes lately. I have some really cool announcements which I will give more info on later, but here is a high level list of cool happenings with the Total Nuclear Annihilation project.

Name Update

This project is now called Total Nuclear Annihilation in order to distinguish itself from the 1990’s video game.  These are not the same!


Yes, you heard that right.  Total Nuclear Annihilation will be produced!  Although this was not my original intent, Spooky Pinball has agreed to work with me to get this game into your houses and bars near you.

Spooky Pinball Podcast

I appeared on the Spooky Pinball Podcast this month and we talked about all sorts of pinball stuff.

Listen to it here:

Artist Stuff

You guys already know this, but art is not something I do well, even though my mom is a professional ceramics artist, this did not flow well down the bloodline, and definitely does not mean I know how to do awesome pinball art.  🙂

Matt Andrews will be doing all the art for Total Nuclear Annihilation to bring it to the next level!

More info on Matt Andrews here:

Graphics Stuff

I am also proud to say that David Van Es will be doing the LCD animations for Total Nuclear Annihilation as well!

TPF and MGC were awesome

Thank you to Ed and team at TPF and Dan and team at MGC!  I had an amazing time there with the machine and am glad I had the opportunity to show it.

Southern Fried Gameroom Expo

Total Nuclear Annihilation will be at SFGE this year on June 9th – 11th at the Spooky Pinball booth.  I will also be there playing dollar games.

Dead Flip Stream (5/12/17 @5pm CST)

Dead Flip will be guests again at the Sleepy Nut Tavern and streaming the Total Nuclear Annihilation whitewood machine!

There are lots of new features and graphics, so make sure to tune in.  There also may be a hint at what the artwork will look like.  🙂

Stream starts at 5pm CST.

Thank you

And, a big thank you to everyone for the great feedback on the game.  I really appreciate it and I love watching you guys and gals enjoy the game.  Thank you once again!


That is about it for now, I will update again with more details soon!  Thanks for following!



Hey Everyone,

Just a friendly reminder that Total Nuclear Annihilation will be at the Multimorphic booth this weekend at the Texas Pinball Festival in Frisco, TX!  Come by, say hi, and play the game.  I am good for free high fives if you need one.  See you there!
