That does not look like the same diagonal lines @Headrush69 was talking about. If it was an artwork issue it would be a static line since the artwork is just an image overlay. Artwork issues in Mame usually look like the image below (static diagonal lines). Does that affect show up on every game? If so maybe try changing the video driver your mame is using.

It's true, those lines are not the same problem.

Dots appear on my screen and go down diagonally.

I attach my artwork directory and a video showing the problem.

If you are seeing diagonal lines across the screen in MAME, it's like a problem with missing artwork be used by a MAME layout file.

It's exactly the problem. Diagonal lines across  the screen. Then is a mame configuration into Emulator Manager from Launchbox?

Hi. I have a problem. If I launch mame ROMs with mame emulator, ROMs work fine, but if I launch mame ROMs with launchbox (with the same mame emulator), ROMs show graphics problems.

Can I configure any options un mame ir launchbox to fix this problem?
