@mitu OK, strange, but I tried on a different laptop and it works fine. Made the backup. The other sd card backed up just fine on the laptop that this sd card would not. I'm not sure what the issue is, but it is done ... both sd cards backed up. Thanks again!

@mitu That did it, thanks so much! :)

Because I don't want to lose all navigation sounds, I just don't like these specific ones, I think they sound tacky. Plus they vary in audio quality and volume.

Replacing them with a silent audio file is definitely an option if I can't find a way to stop it from trying to play them.

Ideally a way to edit the theme so it doesn't try to play them at all.

Hi.

Tried both MAME emu and Cannonball.

Will get the lowdown on all the details for you and let you know..

Topic moved.

@Efriim yeah I did.
Use this exact power on other pi’s too

@mitu Thank you. I sorted it. I changed the TV itself to "external speaker" only and the Pi to hdmi. It seems to work fine now. I get no audio at all when I choose "3.5" or "auto".

@Efriim cool will do!

@Dwarfboysim thank you for your help, I did all the installation from the start and it goes well.

have a nice day :)

@mitu turns out some of the neo geo roms were duplicated in the arcade folder... simplest explanation right? lol

@mitu @caver01 Thanks guys!

ok i tried it. This is my config. But it didnt work. my idea for the select Button is to push the eft and right shoulder button at the same time

DPad U = hat(0 Up) DPad D = hat(0 Down) DPad L = hat(0 Left) DPad R = hat(0 Right) Start = button(9) Z Trig = button(7) A Button = button(6) B Button = button(8) C Button U = button(0) C Button D = button(2) C Button L = button(3) C Button R = button(1) Y Axis = axis(1-,1+) X Axis = axis(0-,0+) R Trig = button(5) L Trig = button(4) Select = button(4) button(5)

And oddly enough I am attempting to duplicate all of these steps on my Pi3 setup and I am back to where I began. Except now the WAD Header error has a lot more garbage at the end than ever before.

EDIT: This only reflects the Run Command method.

I came across this exact issue this weekend. My situation is, honestly I was curious about having OctoPi for my 3D printing and RetroPi to test some games.

To keep it short:

I was using a 128gb Samsung EVO SD card while dual booting (using berryboot)with Retropie and Octopi. After trying to get it working by uninstalling and re-installing amongst other things, I decided to try another 32GB SD card also a Samsung Evo. I installed RetroPie (From berryboot) first. Verified that the images booted successfully. I added the octopi image from the berryboot images page and copied that over successfully. I applied updates to RetroPie first then to OctoPi. After configuring OctoPi to the way I needed it (after many hours of researching) after rebooting, both images still booted with no issue. I made a backup of the SD card with my desired setup then restored that backup to the 128gb chip. I plan to test this chip to see if I have the same results.

Sidenote: In further research of this issue, the problem seems to be with permissions. This command seems to have worked for those getting the error. A reboot was required afterwards:

sudo usermod -a -G video yourusername

I have the same setup as you (mostly) and had the exact same problem. Do what @mitu said, set gpu memory split to at least 256MB.

Take a look at this recent topic - https://retropie.org.uk/forum/topic/22337/gamepad-calibration-problem/3. If the emulator is using the new evdev api to read/access the gamepad, then jscal doesn't have any effect.
