I know what you're talking about. That's the MESEN emulator. It's supposed to be cycle accurate which means it's likely too processor intensive to run on the pi. There is a libretro port for it, but it doesnt seem to appear in the retropie selections. Maybe look in the experimental cores.

@eldrethor yes i didnt think of it... 2003 mame are ok yes.

@neo-rio said in Looking for SD card size advice:

Without any CD games, 128GB is all you need. I have full collections of all major systems and a few of the working experimental ones all fit within that limit.

I find that 128 GB is a bit much, and if you don't count any CD-based consoles, 32 GB is more than enough for the average user, especially if he/she isn't intending on adding full collections to the card.

@udb23 Thanks!

@markyh444 said in Pi 3B. Installed Pixel UI but 'SD Card Copier' is missing under Accessories? Help please.:

@njweb Win32DiskImager is perfect for backing up your Pi. Most people on here use it, and I've made about 10 copies of my SD cards over the years when building and testing new things out in various projects.

I'd highly recommend ditching whatever image came with your Pi though and starting with the base Retropie from the site. If you run into more problems and ask for help here it wont be supported, plus nobody will know what has been done to the image before it was sold to you to try and help you if we can.

If you are happy with tinkering and exploring things for yourself though, you wont be disappointed with starting from the image on this site and making it your own!

Good point, thanks. Just concerned with potential compatibility issues with EmulationStation and installed emulators, settings etc. if I upgrade Retropie (will look up steps again).

Not a chance

@beltet Please give more details about your setup - https://retropie.org.uk/forum/topic/3/read-this-first

@rthorntn Switch the RetroArch video driver to sdl2 or try logging in with a Wayland enabled session. See

@mitu That just gives me a segmentation fault. If it's too much trouble then I'll just try asking the person that compiled lr-mess successfully and hope that he can share it. The reason I wanted to try is because the person said he could succesfully run neogeo cd chd games. If latest mame can also do this now, I wonder how much work would it be to backport it for the mame2003-plus guys.

@mitu again you rock!!

After watching the video in your link, I found where I needed to turn off the OMX Player. (even though he syggested it be on) It is off and now I see the video preview!!! Love it. Thanks a lot. I still do not see <video> tags anywhere though.

@bruno_mlopes IMHO if it's a Debian/Ubuntu based distro, RetroPie would work with minimal fiddling, so if you like Xubuntu - keep using it.

@mitu
I was using 9zip to unzip the image and it wasn't unzipping the entire image file for some reason. Decided to, as an experiment, use winrar instead and I noticed the image file was a different size - I'd not even thought to check this.

@logan71f100 Thanks for sharing the workaround.

nobody can help me?

I tried to reconfigure from within retropie, and for some reason the changes weren't holding correctly. I suspect it was probably permissions related, though I'm not sure how the permissions on the .cfg could have gotten messed up.

@nowun said in <SOLVED!> Retropie with C4 labs galaxy LED case mod.:

@clyde Thank you! That worked perfectly. I added "sudo python /home/pi/caseled/galaxy.py &" in before emulationstation and it boots up like a charm pre loaded with the settings I edited the script for the LED's.

If the script doesn't need administrative rights, you can omit the sudo before the command. It adds a tiny yet easily done bit of security to your system.

@red2blue If the problem is physical, then re-formatting will not bring in additional performance. You're free to save the data from the disk, format as Ext4 and re-try.

@rascas the issue was one of my controllers that was plugged into the pi.. no idea why but once i unplugged that one from the pi it worked.

@jorgenjl Get a Linux live distro (Ubuntu/Fedora/etc.), write it on an USb stick/CD and boot it up on your PC. You'll be able to read the SD card's contents to copy over your configs/roms, then write the latest RetroPie image on your SD card and transfer over your data.
