Ok, here's a long Japanese video where the PSG-generated sounds seem to run at double speed compared to various older MAME videos. Listen to the insert coin sound in particular: https://www.youtube.com/watch?v=q-UDlQTQF0c
And here's another video from the same person who posted the other video of the glitched PCB previously linked: https://www.youtube.com/watch?v=t-CW6uUIhag
This may not be as open-and-shut as Arkanoid, perhaps there could have been some official boards with the YM2149 (with the half-speed pin setting) and others with the AY-3-8910. Maybe this would ultimately need to be implemented as a machine setting, like that Astro Blaster wire mod that turns the starfield from blue to black.
And I'm still not sure if we're even talking about the same issue, or if the speed/tempo of the FM music has recently increased also. Of note, Hamster's Arcade Archives release seems to have the music at a slightly faster tempo than any of this actual PCB footage: https://www.youtube.com/watch?v=Wjaur49yziA
However, it doesn't sound double speed to my ear, and I can't tell if it's faster than other MAME videos on YouTube. (And strangely enough, I have found some videos of the Hamster release with the slower insert coin sound, and others with the faster one. Did the speed change in a patch at some point? Beats me...)
Another interesting thing I notice: On the Japanese arcade video, the cars make a sound when they get shot and spin out. The glitched PCB video has it too. I have never heard that before. (They're missing from Hamster's release too.) Can a dev possibly look into why this sound wouldn't be playing in MAME?
