Summary 06579: fantjour, gokuparo: Slightly distorted/scratchy sound/artifacts
Description I have my system hooked up to a reasonably high end sound system with HDMI, providing crystal clear sound.
Fantjour/gokuparo sounds noticeably bad, especially if many samples are played at once. There are also artifacts whenever screen elements fade in on out (like the title logo)

I usually use portaudio for sound output with a latency of 2, but using default SDL audio and increased latency doesn't make a difference.
Steps To Reproduce Play the game and listen to the audio
Additional Information I have recorded the intro and demo that demonstrate the issue. You can see loud spikes in the waveform whenever artifacts occur.
You can listen to it here > https://soundcloud.com/ralf-van-bogaert/gokuparo (although soundcloud appears to have compressed the waveform slightly)

It seems to be fixed? If I had to guess, it's one of superctr's updates to TMS57002.
*edit* indeed, fixed August 18 2018, superctr improved Taito ZSG2 and TMS57002 at this time.
