MAME Games Cutting Off at Top and Bottom

[lepactedesloups]

Hello,

I am not sure if this is restricted to running MAME through Launchbox, but when I am playing some of the MAME games, the tops and/or bottoms of the games will get clipped off either by the overlay or the edge of the screen itself. When I run a test pattern on the TV, it's NOT getting cut off (so this already a mystery to me). I was wondering if there's any type of fix for this.

I am using Launchbox, launching the MAME games via MAME64. I have messed with the D3D Options in there bit (there's some distortion you can probably see in the images, but I don't like adjusting the value more than a bit). The cabinet I am using uses a 32" 1920x1080 LCD TV. Yes, I know using an original CRT would be optimal, but I was hoping there's some kind of compromise here.

Pictures of what I mean below.

Any suggestions? Thanks in advance!

I think that is part of the bezel to simulate how crts were often cut off a little.

Hit tab in game to bring up the MAME menu -> go to Video options -> turn off bezel and see if you see everything now.

Thanks for the suggestion, but this has no effect on the "cut off" area at the top.

I know I can use the slider controls to mess with the "Horizontal Position", but then it just pushes the bottom off the screen. I don't want to stretch the image or squash it either. Is there a way MAME can just scale the entire image in aspect to not be right at the edges?

A follow-up for future users running into the issue. By changing the horizontal stretch to 0.990 and the vertical to the same, it appears to fix the issue and keep everything in aspect. Only annoying thing is this is accomplished through the Sliders menu, which means I have to do it once for each game I need to adjust (then it's saved to the game's cfg file). There's no way I've found to do this globally.

All's well that ends well I suppose.

Have you turned off "Crop" in the video/artwork settings in mame?

[Headrush69]

Are you using HLSL, BGFX effects? (Looks like it)

What happens if you run with them off?

I've always had the impression that 10 Yard Fight did this as well. 

Native to MAME, before even loading into Launchbox or Big Box - the title screens have always had text that looked 'cut off' by the screen. I've never really looked further into it as it doesn't totally upset game play - but I've always wondered...

Has there been a fix for this? I'm running into the same problem. (Mame 0.264)

Check your command line for MAME in Tools > Manage > Emulators... and see if you have the following command being passed "-artwork_crop" (without quotes) and if so remove it. This command line ensures the game takes up the most real estate it can on your monitor and so if you have artwork that wraps around the play area it could get cut off with this command line argument.
