Hi Kevin,

That sounds awesome!  I will have to try it soon.  I'm going out of town for a
few days so I'll give it a spin on my return.

I did manage to install Ubuntu 18.04 64 bit and it seems to work well on the
VE900 with a 1920x1080 TV acting as a monitor.

I managed to get mame running with "sudo apt install mame" and was playing
about with pacman.

It's a bit slow at 1920x1080 resolution, so we can speed it up a bit if we go
to 800x600 or 640x480 resolution.

mame pacman -autoframeskip -resolution 640x480 -switchres -sdlvideofps -video

will give me around 30 frames per second.  Interestingly, at 640x480 the
"-video soft" gives about the same performance as "-video opengl".

For some reason the very top gets chopped off by the TV when I run mame from
1920x1080 mode and put it into 640x480 with the -switchres and -resolution
640x480 options.  I activate the mame frameskip display with F11 and it can't
be seen.

When I run it from 800x600 mode by doing a "xrandr --output VGA-1 --mode
800x600" first the TV will display the mame screen properly.
