This bug affects Exerizer and Sky Fox... 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...

OK disregard that last video. I figured out how to plug in directly to the PC... It's still gray scale but it's much clearer now. You can see what the starfield needs to be doing more easily now:

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.
