Repeated process

When you have finished above you can now just edit the script.txt file with your new game ID and start the download process for any game/server:

1. docker run --platform linux/amd64 -it --rm -v "steamLogin:/root/.steam:z" -v "$PWD/dl:/steamDL" -v "$PWD:/cosi" steamcmd/steamcmd:latest +runscript /cosi/script.txt

i keep getting "exec /bin/sh: exec format error"
im on the latest image (Linux raspberrypi 6.1.0-rpi7-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.63-1+rpt1 (2023-11-24) aarch64 GNU/Linux)

Anyone got any hints?
#Solved it by doing postinstall

and made sure i ran, docker run --privileged --rm tonistiigi/binfmt --install all

Had to use @sSteamCmdForcePlatformBitness 64 inside steamcmd

I'm having an issue at the very end , when it's supposed to install the game it says that it requires a 64 bit system but I mean , the whole point of this tutorial is to emulate 64 bits right ?

After the command :

what is a gameID

the whole point of this tutorial is to emulate 64 bits right ?

No, the Problem is that SteamCMD doesn't run under the ARM architecture, which the Raspberry uses.
This Problem get resolved by this way.

what is a gameID

A Number which identifies the Game. Can be found in the Steam URL of the Game ore with the following website.
