Update as promised;

– Modify /etc/emulationstation/es_systems.cfg so that the uae files are recognised.

<extension>.sh .SH .uae</extension>

– change /opt/retropie/config/amiga/emulators.cfg to use the config parameter.

uae4arm=”pushd /opt/retropie/emulators/uae4arm/; ./uae4arm -f %ROM%”

– Download the following two files and copy to your amiga roms folder (i.e. /home/pi/Retropie/roms/amiga)

adflist2uae.py
https://www.dropbox.com/s/6opn1gehvnjtvox/adflist2uae.py?dl=0

template.uae
https://www.dropbox.com/s/be230bhjq86he8l/template.uae?dl=0

Now, from the command line run the Python script in the your roms folder

python adflist2uae.py

This script is used to create config files for each of the games in your folder. If a game has only one floppy (one adf file) it will be straightforward
e.g.
StuntCarRacer.adf writes a file called StuntCarRacer.uae, where the first floppy disk is set to StuntCarRacer.adf

For games with multiple floppies, it will expect files in the form GameXXX (Disk 1 of Y).adf, GameXXX (Disk 2 of Y).adf etc

So, if I’ve got

Sensible Soccer (Disk 1 of 2).adf and Sensible Soccer (Disk 2 of 2).df I will get a config file called Sensible Soccer.uae

You have to make sure that the adf files are named exactly the same, except for the floppy disk number.

You should now be able to launch into the games from the Amiga menu in EmulationStation without the GUI. However if you have a keyboard handy, you can return to the menu by pressing CTRL if you need to change the configuration or save state etc.

Unfortunately, I’m not quite sure how to quit the emulator without the keyboard, so maybe we can’t get away with using only the joypad just yet.
