Hey. Sorry for the bump, but I recently built my Porta-Pi bartop arcade using this custom built image for the Porta Pi:
http://www.retrobuiltgames.com/porta-pi-arcade-help/porta-pi-software-os-download/

Mine is the v4.5 download with Retro Pie 2.3 built in as it comes with Raspbian which is 100% necessary for me as I generally loathe command line stuff.

/opt/retropie/emulators/mame4all-pi/mame.cfg

has the improperly formatted samples directory. I changed

rompath=/home/pi/RetroPie/roms/mame
samplepath=samples

into

rompath=/home/pi/RetroPie/roms/mame
samplepath=/home/pi/RetroPie/roms/mame-samples

and it was a life saver. I want to say thank you for the help.

While we are on the topic, can anyone tell me how to reduce the audio lag? There is nearly an entire second of lag between the onscreen action and the sound effects. 3 or 4 frames is fine but at half a second or more in MAME, it can be a bit disconcerting at times.
