Specific system information

Hatari emulator configuration

RetroBat forces Hatari standalone to use the configuration file located in \emulators\hatari folder of the RetroBat installation.

When making configuration directly within the emulator, ensure to configure it by using the .bat file provided:

Standard hatari.exe stores the config file in "userdata" folder of windows, changes done in this file will not work when running from RetroBat.

Mounting a "gemdos" hard drive image

Libretro Hatari-B core can automatically mount a "gemdos" hdd image within the emulated system.

In order to do this, the hdd to mount must be stored in the roms folder :

Next, create an empty text file in the same folder, name it with the exact same name as the folder and save it with the .GEM extension:

Additionnaly, it is possible to make lr-hatarib automatically run one of the program stored on the mounted gemdos HDD image.

To do so, create an empty text file in the roms\atarist folder that is named with the exact same name as the gemdos folder.

In the file, specify the following information:

#EXTM3U
#AUTO:
<name of the GEM file>

Finally: save the text file with the ".m3u" extension and place it in the same folder as the image folder and the GEM file:

In this example, RetroBat automatically:

  • Launches hatarib and mounts the "The New Zealand Story" image in the emulated device

  • Runs the program RUNME.TOS from the mounted drive (program is located in C:\AUTO)

Running .gemdos folders requires the TOS version 2.06 or emuTOS.
