The starfield is supposed to be doing all sorts of tricks including the whole thing blinking in patterns and even scrolling backwards at parts. I made a video of a real Jaleco Exerizer board running. It's in grey scale and has no sound but it's good enough to see what the starfield is supposed to be doing. I can replace it with a color video in a few weeks... http://smitdogg.mameworld.info/mametesters/exerizer-bw.wmv

It's still gray scale but it's much clearer now. You can see what the starfield needs to be doing more easily now: http://smitdogg.mameworld.info/mametesters/exerizer-hq-bw.wmv

No.17221 sasuke Tester Nov 28, 2019, 14:06	Fixed in Version 0.217GIT. Please check the attached video. I think pixel pattern and scrolling are correct. but blinking pattern may be a little different. I cound't completely found blinking logic.
