I had avoided snapshot because in some moments the background flicker. Is easy to see the issue. Just start a game and wait CPU select the characters Reiji, Annie and White Buffalo. Thanks.

And looks like the background objects are not synchronized well, but it is really a MAME issue? You must prove that the original PCB doesn't work like this.
No.13634 Fujix Administrator Feb 16, 2017, 10:31	Here I found a recording of PCB http://nviewer.mobi/player?video_id=sm13501430 I think this is an original behavior.
No.13636 Augusto Tester Feb 16, 2017, 20:21	Excuse Fujix and Tafoid ... my system is without image editing software. In next time will try another method. Background objects issues is recent. I not see the issue in previous versions. My post is just to say about the issue. Thanks blessed Fujix and Tafoid .. your acts are much more value than see a report for gameplay.

No.13654 Fujix Administrator Feb 20, 2017, 03:45	I checked in some old versions back to 0.135, all work the same as in 0.182. Augusto, I used all free softwares to create the img.

No.13678 Augusto Tester Mar 3, 2017, 02:19	You has selected Reiji and use double jump in Reiji stage and I not see backgrounds issues. Seeing the video in 1:44 another detail is that in logo screen not has squares. MAME display square in logo screen. ID 06256 http://mametesters.org/view.php?id=6256 Thanks Hammy.

"mame64 powerins -gamma 0.8" mimics a gamma level closer to most arcade monitors.

No.13714 Augusto Tester Mar 19, 2017, 18:55	Seeing that need to change the post title because has another games with the same issue. Golden Axe in stage 7 and 9 background has issues. I need see again to confirm about Truxton .. in moment that the background is just space background stars move with strange effect, but how I say need to confirm. Have anothers games with same issue ... I need remember which are the others games and confirmed perhaps is a issue in video render or a emulated graphics processor.
