First Look: Bally Silverball Mania – Original rules vs BSOS updated ruleset

This is a short video where I go over some alpha code for the Bally Silverball Mania classic pinball machine. I demonstrate the original ruleset of the game, then show how a re-programmed BSOS system changes the rules and fixes some problems with the original gameplay design. The result is a much more balanced game that can be used in competition and is more fun and challenging to play.

Demo of Custom Paragon with all new Sound/Rules

Here is a short update on the progress with my 1979 Bally Paragon pinball machine with custom rules and sound. The game is close to being complete. Take a look!

I’m now at the point where I’m getting various feedback from players about the content. Most people like it, but some seem to think the music is a little too “mellow” given the theme? I can see that. I wanted to do something a little more stylized and different. You’d probably expect some kind of dramatic orchestral score with the game, and not a kind of funky prog-rock type of music. So I’m torn on whether I should keep it or change it? I’m going to talk with the artist and see if he has any ideas — maybe we might record something specific for the machine? I don’t know, but I do like the idea of using a real band that we’ve actually recorded – so every sound in the game was completely created. Let me know what you think?

BSOS Custom Paragon Pinball Update – New Modes!

Here is an update to my progress completely re-coding a 1979 Bally Paragon pinball machine, with an Arduino Nano, with all new rules and operating system. This game will be an enhanced version of the original with extra features and deeper modes, and 14-channel polyphonic CD-quality sound.

Building a custom micro-controller for early Bally/Stern solid state pinball machines

This is an introduction to an up-and-coming technology that a small group of pinball and electronics enthusiasts are developing. A custom microcontroller that interfaces with Bally-35 MPUs and allows you to write customized rulesets, even completely re-theming games. This is the first part of a journey that I hope to take everybody on.

NOTE: This is a video I recorded several months ago that I forgot to make public, so I’m much further along.. But thought it might be interesting to show this early look at the development of this technology. Now there are etched boards that can be acquired.

What’s involved in programming a pinball machine?

After restoring a vintage 1979 Bally Paragon Pinball, I go on a quest to see what’s involved in re-programming a game like this and doing my own, custom ruleset. You may be surprised at how many things you have to take into account and keep track of. Let me show you some early progress trying to hack a pinball and re-design a new operating system and set of code.

This video goes over some general, philosophical considerations in pinball design. In future videos I will dive in deeper into the specific technology and coding.

Quick demo of fully-modded Stern “Trident” pinball with new rules and sound

After getting my Trident operational, I installed the BSOS system and have been working on fine-tuning the custom code and sounds. Here’s a short demo of what the new Arduino-based controller does to a standard Bally 18/35/Stern early solid state game.

Resources (courtesy Dick Hamill):

The code is all available on GitHub. It’s broken down into a base library and then machine-specific implementations. Rewriting other games requires a moderate knowledge of C/C++.

Here’s a suggested parts list. If you bought all these things, you could create 6 of these boards. If you don’t need that many boards, you might find cheaper ways to source smaller quantities. I haven’t done any work to figure out if this is the cheapest way to source any of this stuff.

Cheap Arduino knockoff x6 ($20.99) – needs CH340 driver for programming / has to be ATmega328P
