Summary	05225: Graphic glitches after moai stage in Gradius II
Description	After finishing the fifth stage of moai in Gradius II, a background graphic glitch always occurs. If losing a life before the glitch occurs, enemy sprites will glitch as well after you return. It is not the same as 03756 since the previous one has nothing to do with enemy sprites. See the movie uploaded.
Steps To Reproduce	The graphic glitches occur at the beginning of stage 6. The first background graphic glitch always occurs. (See the first picture of the uploaded file) The second glitch only happens when losing a life before the first glitch occurs. (See the second picture of the uploaded file)

No.09638 Mamesick Senior Tester Jul 6, 2013, 18:50	Fujix is right. It's the same issue. BTANB. I would close this.
No.09640 alexhiro Tester Jul 7, 2013, 03:04	It's not exactly the same. I uploaded a movie to show how enemy sprites got glitches. They may related but the previous entry has nothing to do with enemy sprites.
No.09641 Mamesick Senior Tester Jul 7, 2013, 14:25	Yes, ok, but until you cannot provide a real arcade video of the issue, we just assume that also the enemy sprite glitch happens on real hardware and it's not a MAME bug.
