there is a package available upstream for both cosmic and bionic, would it be possible to maybe fix the script to not add the broken repo for cosmic?
The repo is mainained by the FS-UAE author and it's the recommended way to install it (https://fs-uae.net/download#ubuntu). If anything changes regarding that, we can also update the script. While for 18.x the latest package is upstreamed (Ubuntu), for older releases the PPA has the latest version. Let's see what happens when 19.04 breaks loose.
If interested, I can also raise another PR at some point regarding my post above, where I have custom launching scripts for A500, A600, A1200, and CD32 and a modified emulators.cfg to suit. Maybe you can take a look at it and see if you are happy to add it in. I know it's x86 only and probably not a priority but I think it improves on the defaults for those who use it.
@dirty_monkee This issue may be of interest regarding the “Volume DH0 is write protected” error.
The best chance of success is to use RetroPlay's WHDLoads as this is what the Amiberry WHDLoad Booter has been designed for. The name of the WHDLoad I am using for SWOS is SensibleWorldOfSoccer9697_v1.7_0842.lha.
I wouldn't recommend using floppies - check the page for Loading from Disks (ADF) at the Amiberry wiki.
If you're interested, I've documented a slightly different way of achieving FS-UAE integration with EmulationStation here.
The nice thing about my method is that multi-disk games work just fine and EmulationStation only shows you one game entry. This is because we directly query the local FS-UAE database for the details on the games you have.
I'm slightly biased, but I think it works rather well - not only with Amiga games, but also with CDTV and CD32 games.
