So, I pretty well had everything set up the way I wanted, but wasn't happy with my MAME layout. Downloaded Sardu's "gameroom" layout from the MALA website, got it configured how I wanted it and....
MALA crashed when I first opened it. The culprit is the emumovies videos as when I remove the "video" object from the layout or change the video folder target, everything works like a charm. It will even play the NES/SNES/Genesis videos without issue.
So, why would changing the layout and nothing else cause MALA to crash when playing a video only on the MAME layout? So frustrating...
The only codec I have installed on the machine is XVID, so it shouldn't be a codec issue for the record...
