The Launcher only downloads some RTB files for the kickstarts (files with additional information about the kickstarts). FS-UAE Launcher will also copy the correct kickstarts, but this requires that you have those kickstarts indexed in the FS-UAE Launcher file database. So if you use “Scan Files & Configurations” from the database, you should have a green checkbox for A500 at least. I cannot distribute the kickstart files, so the Launcher cannot automatically download those.
SetPatch will be copied in if you have a Workbench 3.0 disk indexed. I cannot distribute copyrighted Workbench files. This file is not always required, and the boot process will continue without it.
