Well, I think there are three separate issues here:
[1] The YM2203 is running too fast (I think ajrhacker did a commit on github that will fix this?
[2] The PSG chip is supposed to be an AY-3-8910, but according to a comment added by AJR with his previous change, at least one board has been found with a YM2149. There is video of an actual machine with the insert coin sound running as fast as it does in 0.193, but there is also a possibility that there could be YM2149 versions with the PSG sounds running at half-tempo (but not half-pitch, like Arkanoid does; the pitch of the "fast" insert coin sound is exactly the same). AJR, has the YM2149 PCB actually been run and tested?
[3] The sound of the cars spinning out is missing, and removing the comment from line 52 of the driver causes it to play as it does on video footage of real machines. AJR, can you look into this too?
