Continue with what you have to #4 in these instructions.

In this line of code:

# get parameters direction="$1" system="$2" rom="$3"

I changed it to:

# get parameters direction="$1" system="" rom="$3"

Too many folders are created with the first option.

Also, be sure to make the necessary location changes in these:

# path to RCLONE rclonePath="/home/pi/rclone-v1.39-linux-arm/rclone" # local base directory for your saves localPath="/home/pi/RetroPie/saves" # remote directory for your saves, has to be configured via "rclone config" first remotePath="dropbox:RetroArch"

One thing to mention, if for some reason your Retropie is offline, your system will freeze and you will need to power it off.

@dankcushions Here are the 100 core option files I made for the 5200 content I have. These are the .opt text files only.

Core option files for 5200.zip

I put them in \RETROPIE\configs\all\retroarch\config\Atari800\ and so far I think it's working although I haven't tested all of them.

Any specific reasons to use RetroPie for that? If you are only interested in Amiga Emulation, maybe this Project: Amibian could be a suitable alternative for you.

Otherwise, maybe a modification of the scripts mentioned in this topic: Autostart last played game could be used ?
