Summary	02052: xmultipl: On the PCB you can (partly)see the bubbles/balls on the titlescreen during the flash
Description	On the PCB the titlescreen shows during the bright flash the relief of the rotating bubble/balls logo... it's a bit hard to explain but i think the picture of the monitor and movie (capturecard) will more understandable. The slowdown during the movie is not a PCB fault, it's just because i could not sync a stable picture.
Steps To Reproduce
Additional Information	In the attached AVI, you'll see the flash at about :12 in. This doesn't happen in MAME.

No.01834 Kold666 Developer Jul 28, 2008, 22:06	it seems the same problem with the m62 games where you can see the silhouette of the hair of kid niki on the black background! M72 schematics are available, maybe someone can see if there a similar colour circuit to m62 hardware?

No.08215 Stefan Lindberg Senior Tester Feb 19, 2012, 18:04	It is always scrolling jerky in MAME as it is 55hz :-)
No.08217 haynor666 Tester Feb 19, 2012, 20:08	That's not the case because I'm running this at 55Hz (custom resolution). The first planes is scrolling a bit jerky for me (it's clearly visible in attract mode on level where background is black. For example R-Type and Legend of Hero Tomma are ok - first bitplane scrolling is constant.
