Only the audio lags noticeably in MAME. If it was video too, the games would be unplayable. I’m running the Raspberry Pi 2 @1.0Ghz basic overclock setting.

It can get rather annoying to say see my ship blow up and then hear the explosion effect. Same with bullets, running or jumping in Donkey Kong, eating ghosts/fruit as Pacman, etc. Do pretty much action with an associated sound effect, and there’s a noticable delay between the the video and audio.

The console emulators do have global settings to adjust the audio latency. I whittled it down from the default 64ms to 40ms without issue. 36ms makes the games stutter. MAME needs it’s own configuration separate from Emulatrion Station and I don’t see any setting to adjust the audio latency which is noticeably huge (0.5-1 seconds) and affects all games. Somebody also suggested to change the sample rate to 44100Hz. I don’t know where this setting is located or which file to edit.

I should probably start a new thread for the audio latency issues… :p

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.

Hi. I recently bought and assembled the 10 inch kit. Ryan Bates currently has two images available on his website which are compiled for Raspberry Pi 2. One of them comes with Raspbian and is preconfigured for the GPIO module. The other is a more recent bare-bones Retro Pie installation with no OS and no input config. I downloaded the one with Raspbian preconfigured.

Overall it works great but I’m having a few issues with the MAME emulation. That’s a topic for another thread though. Cheers and I hope you got it figured out.
