EMULATION
ATARI ST
If you just want to boot into an ST, Aranym basically simulates an ST wholesale. It was in our repositories, but needed a system ROM to start. Enter EmuTOS, an open-source TOS replacement that even works on a real Atari ST. Grab the EmuTOS tarball from http:// emutos.sourceforge.net, and then copy the contents into Aranym’s config folder in “~/.aranym.” That should sort it.
Hatari is like most emulators (well optioned), rather than a straight simulation—you can find out more at https://hatari.tuxfamily.org. It’s probably in your repositories, but will need its own TOS image as well. Once again, EmuTOS can provide that.
AMIGA
The most popular emulator is FS-UAE, which should be in your repository, but make sure you install the launcher package as well. If you’re running without a custom system ROM, make sure you set the machine to emulate the Amiga 1200, as this will guarantee the best compatibility. https://fs-uae.net
DOSBOX
Used all over the world, DOSBox is a DOS emulator that runs everything and is available on a zillion platforms. It will undoubtedly be in your distro’s repositories, and you won’t need a BIOS file for it. However, it does take a few steps to get it going like a normal DOS machine.
We won’t show you how to use DOS, but we will show you how to set up your C: drive. DOS used a simple file called autoexec.bat to run its startup commands, but DOSBox doesn’t actually have this file, nor does it start with a C: drive. You need to edit its config file to emulate autoexec.bat and assign a C: drive.
For this demonstration, we’ll assume you’re putting all your files in a folder called “/dosbox” in your home directory—this folder will be the C: drive. If you enable hidden files in your file manager, the DOSBox configuration is in the hidden folder “~/.dosbox.” Scroll to the bottom of the file, and find the section [autoexec], where you put in your lines to execute at startup. Add these two lines, and DOSBox will now start up with your C: drive ready to go: mount c ~/dosbox c:
