[Haze]

the reality is almost no arcade games run at 60hz, just in most cases nobody has bothered to accurately measure / calculate the variables which determine what the refresh rates should be.

The office of internal FBA affairs (aka Gab75) is taking care of replaying gradius II to get me a state. 

Regarding the hz: leaving some games at 60hz was intentional on my part.  Also, iq_132 leaves some games at 60hz also, for either the same or different reason than me.  Is this a big deal?  if it is, I'll change them, but probably a good 80% of the drivers run at a solid 60hz which means a lot of dull work...

Many years ago, before you started fixing up sound cores, a lot of them crashed at anything but 60hz. I've gotten into the habit of just leaving them at that

There's a problem with Darius bgm, drums in particular can go really loud and sound bad.
The 1st stage doesn't exhibit that, you have to reach zone B (up after 1st boss) to hear what it is about.
It's really awful at the sea stage (I think it was zone K when going always up after bosses).

It sounds better in Mame, hard to find a real arcade video with great audio.

I was playing Darius (Extra) (Japan).

edit: I did a video capture in the sea zone, 1st boss down, 2nd boss up way.

Thanks   I'll have a fix soon.  It looks like we were only playing the drums out of one channel - oops.

Hi,

It seems there are graphical glitches in king of dragons (in multiplayer ?) : https://www.twitch.tv/videos/321325247 (see bottom of screen at 00:33 and 02:07).
While the video is most likely from netplay in the libretro port, i don't think it is related.

Thanks
Tonight I'm back doing bug fixes, the ccastles driver tied me up for a couple days.

barbudreadmon, check pm - I think we took care of this issue with the recent timing changes
edit: verified w/old and new exe: yes, the timing changes take care of this issue.

Tatsuya79,
Darius should be fine now (as soon as the second fix makes it into the lr build).  There were 2 problems:
it was only outputting sound on one speaker, and due to some timing issue, the digital samples were being slightly distorted.  Unfortunately the second one took me quite a while to track down.  Thanks for the report!

best regards,

Here's 2 sound samples showing before / after digital audio bug in darius.  The clip is from the boss death.  Notice the clicks and distortion in "dariusbug.mp3", and the nice "dariusfixed.mp3".  Due to the low bitrate of the samples in the game, dariusfixed.mp3 is as good as it gets (period).

best regards,

Nice work!
Sounds a lot more like a giant space fish agonizing scream.

Stuck notes or volume going down untill there's no sound any more randomly.
Seems to happen after playing 5/10mn.
Happened to me twice in world 2 (2nd time after restarting the game).
