What clock speed is the CPU running on the Alltek when jumpered for Bally clock speed?
People have in the past had issues with S&T boards when they incorrectly jumpered their Allteks for Stern MPU200 CPU clock speeds.

Okay -- easy to try a longer delay. I can put it on a define to make it configurable as well.
If tktlwyr can reflash the Arduino easily enough, perhaps they can test for us.

They were all (MMPM, FG, and Xenon) set to Bally clocks. I verified with pics I had on my phone just now.

The MPU board cycle times I calculated were based on the same code DickHamill posted. Note Elektra uses the same code so timing should be the same.

Has anyone looked at the S&T code to see what wait times it's using?

I can test for you. I will be out of town for the weekend starting Friday, though.

tktlwyr , did you compile and load the code yourself, or did you buy a pre-burned kit? If you loaded it yourself, can you run an experiment?
In your BallySternOS.cpp, search for these lines:
// wait 76 microseconds
delayMicroseconds(145);

and change the 145 to 250, so it reads:
// wait 76 microseconds
delayMicroseconds(250);

Then, re-upload to your Arduino and give it a shot?
As you can tell from the comment above ("wait 76 microseconds") this value has been in flux already. Hopefully we can find a delay that works for everyone.

Has anyone tried the new code on a FG that uses the Sounds Plus and Vocalizer boards? If the original 6800 game software is the same for the SP/V units, it would make sense that the Arduino code written for the S&T would work with SP/V as well, but I don't have a SP/V to actually test it.

I just emailed them with the same question. Curious to see what they say.

Should work. Communication is identical between boards.

Just saw this. I’ll play with it this weekend. Thank You!

Awesome! Thanks for the effort!

Picked up a wav trigger so really looking forward to sounds being added

Building some BSOS boards for friends and there's a ? about Flash Gordon. Does the 2021 code include support for background music via a wav trigger board at this point?

I'm building Mega boards for the games where it's an option.

would there be an example for implementation of the wav trigger? No idea how to start there though I ordered a wav trigger for this

Actually the REV 1 and REV 2 boards are both for the NANO. The difference is the REV 2 has some extra logic needed for STERN sound cards. The REV 2 is what I use in Meteor for the 2021 code. The REV 1 is fine for Bally and early STERN games with chimes.

The REV 3 board is the one that supports the embedded MEGA PRO module instead of the NANO.

Just picked up FG at Texas Pinball Festival this weekend. Got a RoyGBev board on order and already have a spare Wave Trigger. Can't wait until we can use sounds from the movie in the game!

geeteoh has a replacement Squawk and talk board that allows you to add custom sounds. I have 2 of them. Work great check it out before you start on your Flash Gordon
Mike

I'm hoping that like my Meteor 2021, I can eventually use the RoyGBev Arduino board with the Wave Trigger to add new sounds without Geeteoh's replacement Squawk and Talk board.

ElCid95 Any update on how you made out? I was kind of thinking the same, since RoyGBev solution gives the flexibility for rules as well.

It's well past my capabilities. I was hoping my post would inspire some of the excellent Pinsiders here to take on the project.

Do I need a programmer to start tinkering with this code on my mega 2650 or does it hook up straight to the PC via usb? I'm just starting out and am a noob here.

You download the Arduino development application, download the game code from GitHub, open it up in the Arduino software and you are looking at the code. USB connect an Arduino Mega and upload the code into it. So from there you need to modify the code to use your alternative sound source, the WavTrigger.

The WavTrigger you insert a SDcard loaded with your sound effects and/or music. The WavTrigger only uses uncompressed CD quality wav files. The BSOS code has been designed to send commands to the WavTrigger to have it play individual tracks, start, stop, pause, loop, set volume, etc.

If programming is new to you this would seem a bit overwhelming. That is where I started from, not a programmer, but slowly figured it out and rewrote Eight Ball that is now being played by people.

The site is gone!?! No examples of the hardware setup or anything, all just gone.

looks like just the rev3 stuff is gone, the other stuff listed in message 1 is still there

I believe it is temporary.

All of the BSOS stuff and the instructions (.io) are gone - as if they were never there. That's strange. I have a download of the master from november, but not the hardware build and other info from the info pages.

Grab the hardware stuff from Dick Hamill threads if you need it.
Did you try dm bluebomber directly to see what's going on with some of the subsections on GitHub?

If you guys are revisiting code again and you get a chance it would be the best of both worlds if 2021 code was compatible with the geeteoh sound replacement board.

If that board works as if it was an original board then nothing special should need to be done to use it,

No grabbing anything from the posts as they all link to ballysternos github which is defunct/gone. The RetroPinUpgrade repositories are missing all hardware info (pcb files/schematics/etc) and .io pages. Have messaged Dick Hamill here, so gonna wait to see what's what. Obviously the repositories were removed for some reason... Anyone happened to have downloaded the repository/io pages before it was taken down?

bluebomber forwarded me the RetroPinUpgrade github address but it only has the code for games, not the base BallySternOS code or info.
