CREATE A VIRTUAL HARD DRIVE
Floppy disks are slow. Attach a virtual hard drive, and loading times are quicker, and you can switch between programs without having to swap out disks. Hatari supports three type of emulated hard drives: ACSI, IDE, and GEMDOS. Of these, ACSI is the most compatible option, and works with all versions of TOS from 1.02 up.
ACSI emulated drives exist physically as an IMG file, and can be awkward to set up, plus they require drivers placed on the virtual hard disk to work correctly. Thankfully, Hatari provides you with an empty 80MB hard drive image, which you can download from https://hatari.tuxfamily.org/hd80mb. image.gz. Extract the hd80mb.image file to a suitable folder, then open Hatari’s configuration, select “Hard Disks,” and click “Browse” next to “ACSI HD Image” to select the file.
Reboot your ST, and you’ll see a new drive C appear, to which you can copy files. Note that many commercial games refuse to run from hard disk. For those that do (such as Civilization), just keep your games in separate folders, and make sure you save your configuration, so the hard disk is always accessible whenever you start your virtual ST.
