Roms won’t load

jkeefe56

Hi, I know this gets asked a lot but I’ve been googling it for two days to no avail....

Did a manual install from raspian desktop and retropie looks good but the roms won’t load (takes me back to game select screen).

Model or other hardware: pi 3b v1.2
Power Supply used: novatel 10w/5v/2a
RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.5.10
Built From: Manual Install from this websites instructions, then chose basic install
USB Devices connected: wireless keyboard only for now
Controller used: keyboard
Error messages received:
Log found in /dev/shm/runcommand.log (if relevant):

Parameters:
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-snes9x2010/snes9x2010_libretro.so --config /opt/retropie/configs/snes/retroarch.cfg "/home/pi/RetroPie/roms/snes/Earthbound (U).smc" --appendconfig /dev/shm/retroarch.cfg

Guide used: (Mention if you followed a guide) guide on this website for manual install
File: I’ve tried 4 or 5 different ones. All worked on desktop and wii emulator, none load here (nes, snes, n64 and atari plus I tried two genesis games that were untested...none worked)

RetroPie doesn't work on the desktop version of Raspbian, you need to use the Raspbian Lite (i.e. no desktop) variant. Which version of Raspbian did you use ?

I believe it’s 4.19.57 (one of those preloaded canakit cards as I don’t have another home pc at the moment to flash sd cards with). I do exit the desktop before launching retropie and like I said all seems well until trying to load a rom.

Try updating your kernel and firmware, do an

sudo apt-get update
sudo apt-get upgrade

and re-try.

@mitu it’s still not working, however the upgrade did have a few “failed to fetch” on the bottom on for chromium, one for libraspberry and one for the kernel. So,...I’ll keep trying.

I did sudo apt full-upgrade and that fixed those errors, but the rom still won’t load. Same error in runcommand.log

It looks like something didn't get upgraded. Can you post the output of the 2 commands below:

apt show libraspberrypi0
nm /opt/vc/lib/libbcm_host.so | grep bcm_host_is_fkms_active

jkeefe56

the second command didnt do anything, the first gave this...

Unless something happened with the latest Rasbian updates, I think there's something wrong with the libraspberrypi0 package installation on your end. Try to re-install it with

sudo apt install --reinstall libraspberrypi0

Thank you so much! It’s working now! Thanks again for the help!
