Colourising Indiana Jones DMD Graphics

So I thought it was time to add colour to the DMD graphics section of my Indiana Jones software rewrite. Colourising DMD dot data has become a new standard for updating of games, with many titles being given the colour treatment. There are a few different ways to do it, but the outcome is the same. I am using the  P-ROC method which was invented by my Friend Eric from Cactus Canyon Continued Fame. He has been helping me out adding the colour data to the raw dot frames. Massive thanks to him. He is a genius! 

Here's a few examples of how it's progressing,

Let me know what you think. Adding the colour really beings the animations to life and also shows off the great talents of the original Williams artist who created the animations and frames in the first place.

80s Pinball Sound Board Revolution

Hi Pinball Fans, Modders and Hackers,

How are you today?

So i've been looking at creating another new board for system 80B games. This time i'm looking at creating a new sound board which will work across the 80B games. It will be compatible with MA-766 and MA-866 series boards and variations thereof.

Been drawing up some schematics before getting some protos made to mess/test with. Looked over loads of schematics from various games and completed the first run of my schematic which will allow the board to work in games meant for the 766 and all revs of the 866 board. There are dip switches to enabled/disable certain sections which are specific to the different board revisions. The main difference is to do with the speech generation circuit. The speech generation for games using the first rev of the 866 board like robo-war and tx sector certainly is an interesting design and some of the games using the 766 board where there was a dedicated speech chip, didn't even use it! Robo-war managed to create that transformers like voice with lots of low pass filtering.

As before with the cpu board i will be looking at improving the design and including similar updates, such as:

- Decent ground anchors
- Test point pads for common signals and voltages
- Leds for common signals and voltages
- Reduced component count
- Plate through design, socketed ics
- Kit option

Also, after looking at a good few system 3 manuals i believe this board will work here to so the full range of games able to benefit will be much higher than originally thought. Again it looks like gottlieb carried on using the 866 board for effects and updated the aux sound driver to improve the speech generation circuit again. Music gen was split across the 2 just like in later 80b games.

I'm interested to hear what people think, who would be interested in buying this board and whether a kickstarter type approach may be a good way to run this project?

I also have an idea for an Ardunio based project where nodders and hackers could use this board to add cool 80s sound effects and music to their projects :) Obviously they would need to buy a set of roms officially from Gottlieb (or their copyright owners)

In Game testing of RFM RGB Super Mod

So things are progressing nicely with the rfm super mod. I worked on getting the proto assembly off the bench and into my game last week and here's a quick video of the interaction of it with the games boot up and then attract mode

Notice how the pattern sequence changes to a fixed colour once its in attract. The mod takes various switch inputs from the game and then analyses them to know what the game is doing. A 'smart' mod.

The heart of the mod controller is an arduino and custom software framework. I plan to release the software framework as open source so that other like minded people can improve the patterns, control of the system and take their saucers in new directions
