Yeah, but I want the Pokey emulation to hear the stereo music.

of course, but at least currently you have a way to gt rid of the glitches and also possibly down the line a fix now there is a correlation between emulation on and the glitches.

Update: the glitches disappear when I disable the Pokey emulation on Subcart.

 

something related with the emulation?

Interesting you mentioning this. I don't have the same hardware setup you do, but I did try for the first time, to play this game with the actual cartridge through my VBXE output last night. I wasn't getting the same glitches that you were showing in your video, but I do get what I can only describe as sparklies along the screen that are fixed in place on some screens and I noticed that the sparkling/twinkling effect of the pixels doing this seem to increase and decrease with the music. It is really noticeable on the title screen. My hardware is a 130xe with the VBXE running the new NTSC palette core and a TKII with dual pokeys for my stereo output. Switching to mono mode didn't change this effect either so it did seem to be tied to audio somehow?

 

Speaking, I have the audio ran separately off the TKII to the left/right inputs on the 9pin mini din I use for my RGB output so it is separate from the RGB although it all uses the same ground on the MD9 output of course.

There is a beta release of the Subcart firmware that includes some fixes for the Pokey emulation. Maybe you can try that? There is a link for it in the Subcart thread here on AA

Have you tried swapping the Ic 74ls08 with a 74f08? Maybe it could

improve the graphics.

I already updated it. Thanks for your suggestion!
