Games not launching

[IceChes1]

I used the master branch from github, following the guide in the Retropie Docs.

You need to give more details about what game/system you're using and post a log file (/dev/shm/runcommand.log) from the emulator starting.

[IceChes1]

I'm in the runcommand menu. How do I get to the .log file?

[IceChes1]

The games I'm trying to use:
NES-Contra
NES-Galaga
NES-Super Contra
Ports-LZDOOM
GBA-Pokemon Ruby
GBC-Pokemon Crystal
GBC-The Legend of Zelda Links Awakening

The only things that work are anything in the Retropie menu and Kodi.

[mitu]

Launch the game, then get the /dev/shm/runcommand.log file contents and post it here.

I unplugged the SD card. It's currently in my Chromebook. SHM is empty.

Yes, that folder (/dev/shm) is RAM backed, so its contents are not actually saved on the card. You need to get the file (via SSH) right after you've run the game.

The only computer I have is a Chromebook. It can't ssh.

Sure you can - https://chrome.google.com/webstore/detail/secure-shell-app/pnhechapfaindjhompbnflcldabbghjo?hl=en.

I'm just a kid. Installing an app is practically a crisis.

[IceChes1]

I've survived the crisis. This is the error:
undefined symbol: bcm_host_is_fkns_active

[mitu]

@IceChes1 Please post the whole file's contents.

What did you use as a base image ? Did you install manually over the latest Raspbian Lite image ?

1: make sure to have bios files.
2: game is corrupted, needs fixing.
When you get taken to home screen the game is missing a required file to run so instead it takes you to home page.

to save your self hassle and pain, install retroarch on pc/laptop and play with your roms on that before you shift them to the pie

[IceChes1]

@mitu I used Raspbian Buster Full and manually installed.
@simonc NES, GBA, GBC etc. doesn't need BIOS. Also, NONE of my games work, so It can't be corrupted ROMs. And for the third thing, I posted earlier that I only have a Chrome OS computer.

[IceChes1]

Here's runcommand.log:

Parameters:
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-quicknes_libretro.so --config /opt/retropie/configs/nes/retroarch.cfg "/home/pi/RetroPie/roms/nes/Contra.nes" --appendconfig /dev/shm/retroarch.cfg /opt/retropie/emulators/retroarch/bin/retroarch: symbol lookup error: /usr/lib/arm-linux-gnuabhif/neon/vfp/libavcodec.so.58: undefined symbol: bcn_host_is_fkns_active

That's it. I nanoed into it after starting Contra.

Well done. Except the error message is most likely about a missing bcm_host_is_fkms_active. It seems like you're using an old kernel/firmware (?). Run this, on the PI, from the command line:

sudo apt update
sudo apt upgrade

let it upgrade everything, then reboot and see if it works.

[IceChes1]

@mitu I have everything up and running. Thank you so much!

@iceches1 what do you mean by this
do I copy this and put it in the command terminal???

[PiKiller]

Yes
