CAX 2025 - my "games of the show"

Yes! Ask an analog synth guy about the CA3080. That's a guaranteed sob story for you.

"How the hell do you build a proper VCA without a CA3080 to give the sound that feel??? HUH??? Nothing else compares to its noise profile!!!"

:ROFLMAO:

For purposes of arcade audio, you don't need that noise profile. You could use another OTA IC. I seem to recall a new modern clone exists and fairly cheap. But I dont remember the part number. And I think there are still dual and quad OTAs available. Or you could build something from transistors. I did that for Vector Pong. Just because. I needed a programmable current source with equal but opposite output values and "no magic bullet parts" was a design objective.


Although I am enjoying the tech discussion, the goal was to find a replacement for the DE0-CV and not do a full redesign.
Since @toledoflyer already knows the Altera design environment it would make sense to port his design to another Terasic board. There just aren't enough buyers to justify a complete re-spin.
 
So now having actually seen a screenshot of this game, QB – 3 is actually pronounced 'CUBE-three'? Cool. I would have never known without this thread. Oh, and @toledoflyer, what's the logic of not starting a build thread on these amazing arcade projects when we are all on a website dedicated to arcade machines? Seems to me that that's the exact thing you should be posting here. Have you done it yet? I'd love to see it.
 
With the QB-3 controls, I'm guessing the left joystick controls fire and the right movement? A trackball still could have been used for movement even though no code for it exists in the program. Atari's home Trak-Ball controllers can be used instead of joysticks, although you won't have true analog movement.

Yes, you could hack in a trackball but if you played the game you would realize very quickly why a track ball would suck on this game. The whole pat your head with one hand and rub your belly with the other trick teaches pretty quickly that it's awkward. Even if you master that one of the key gameplay dynamics is to stay close to an edge and cross back and forth across the edge to rapidly switch sides and avoid enemies. Doing this with a trackball would be much harder to control that fine back and forth movement and timing.

Yes I did do a build thread although it was not nearly as thorough as the ones you typically post since I don't normally do them. I'd post the link here but I'm doing this on my phone and the UI isn't very useful for that.

Who designed the game? I wonder if there was an earlier version of the game that implemented the trackball, but the code to use it was removed. I wonder how hard it would be for a programmer to put that back in.
