16/9 Mame Theme videos in Unified

[darrin1063]

I asked this in another thread but couldn't find a clear answer. I've seen some LB builds on Youtube that show Mame game themes in 16/9. I have an extensive collection of Mame games with themes but unfortunately, the themes are all in 4/3 resulting in them being "stretched" when I try to run in Unified. 

I've searched on Emumovies (I have a premium acct) but can't find many 16/9 Mame game themes.

Is there a 16/9 Mame game theme set floating around or...is there a way to somehow have a boarder in Unified (much like a bezel), where the 4/3 themes would display properly?

 

Btw, new to LB and absolutely loving it!

Have you found a solution to this?
