Summary 08382: djboy and all clones: Graphics glitches in sprites and background
Description Thanks for read my bug report.
Thanks also for Tafoid and Fujix for all work in allowing me post reports.

Screenshot 1 show 2 sprites totally in black color.
In several moments in gameplay some sprites does an blink between the correct sprite colors and black.
Perhaps anyone reply saying that blink is related with cpu character stamina, but if you play not attacking the sprites continue blinking.

Screenshot 2 show some wrong graphics in background.
That bug happen in others moments in gameplay.
Have an nice night.

Regarding the blinking - that is as far as I am aware supposed to indicate that the enemy is damaged and the faster it flashes, the closer to being defeated the enemy is. Confirmed with this video.

The same video at 1:04-1:05 you'll see a flash of graphics which resemble what you show in your second uploaded screenshot. Since this is a video recording from actual hardware, I'm going to assume that such momentary 1 frame issues like this can and do occur and it isn't a bug in emulation.

Thanks very much for adding the YT link.
Video title is arcade PCB not emulation.
