Hi, Firstly I have to say that it's amazing that somebody is working on an Intellivision core for MiSTer. I tried already your latest version with using my Flashback Controllers via Ultimate PC Interface (https://bit.ly/2lPHGhI). Disc and all the buttons are working properly! I think soundwise there seems to be a small issue with the noise FX. It sounds to high and aggressive. I played Skiing and compared it on my original console. Here's a video to compare: https://youtu.be/hdUek9I0F9M The other waveform (Wave or Pluse) seems to sound spot on. Many thanks for all your work in making this core!

Yes. I've used for the sound chip some code I wrote a while ago for Vectrex, without much testing. I'll check the other implementations of similar chips (AY-3-891x)

Noise sound is much more authentic with the latest release (2019-09-21), thanks!

Since the latest release (2021-03-18), there's some new problem. In Auto Racing, the noise at start (tires I think) never stops and continue during all the race. In Astrosmash, the 'tac, tac' is weird, like there's some reverb.
