Bezel Clipping

[Neric]

Hello, I just installed Launchbox (v. 13.20) for MAME v. 275 and imported the roms and the bezels. This is what I get on my Windows 11 with 1920x1080 screen. What exactly do I have to do it fix this?

While the TV surround can cause a very slight clipping if you don't use a shader to match the round corners like CRT-GEOM (the intent of that TV surround), what you are seeing is way more than you should have. What does your lay file look like for this game? Here is mine.

<!-- bezel.lay -->
<mamelayout version="2">
<element name="bezel">
<image file="bezel.png" />
</element>
<view name="Bezel Artwork">
<element ref="bezel">
<bounds left="0" top="0" right="16" bottom="9" />
</element>
<screen index="0">
<bounds left="4.625" top="0" right="11.375" bottom="9" />
</screen>
</view>
</mamelayout>

So it's just a mame layout issue. Thanks mate!

I am having the same issue, running the same version of LaunchBox (13.20).  As I look at it, I think the problem is not with the bezel/overlay, but with the game screen itself because it appears stretched beneath the bezel/overlay.  When I launch the game directly from MAME without a bezel/overlay, it’s not stretched.  This also seems to be the case in the screenshots provided by Neric and dragon57.  Is there a way to turn off the game screen stretching when using the bezel/overlays in LaunchBox?  Thanks in advance for any help with this.

They lay file does affect the games' screen size within the bezel.  When you're not using the bezel/overlay, the lay file isn't being read, thus [it's] not adjusting the game-screen size.

That said, when you have LaunchBox install MAME for you, it adds into the Command-line Parameters -artwork_crop.  You can try removing that (if it's in there) and see if it fixes it.

Also, did you compare your lay file contents with what @dragon57 showed [for vertical games only]?

Deleting the command-line parameter didn’t solve the problem.  I can check the lay file, but I have no idea where to find it.  Can you please point me to it?  I appreciate your help with this.  Thank you!

../MAME/artwork/[rom_name]/default.lay

i.e. D:\MAME\artwork\dkong\Default.lay

I was able to compare the lay parameters and they differ.  Unlike dragon57’s, bounds left=“2” and right=“14”.  I’m not sure how this happened because I imported the full MAME romper using the LaunchBox wizard, which then imported and set up MAME and all the artwork, videos, bezels, etc.

aka: 13.21-beta

Bingo!  It now works just fine.  Thanks for your help with this; I didn’t realize this was a bug that needed to be fixed (and instead thought I somehow wasn’t configuring this correctly).

Mine still has it after putting on 13.21beta3.

I have the same issue. As a temp workaround, I use the Bezel Project Windows installer. Works a treat > https://github.com/thebezelproject/BezelProject-Windows

Thanks mate I’ll check it out.
