How to use
You must first prepare a Hercules configuration file, out of scope for HercUI. For examples see the Hercules homepage or Slackware on Hercules page.
After you have created a configuration file, start HercUI, and choose "Start Hercules" from the drop-down menu and select a Hercules configuration file to use.
The configuration file should have the extension ".cnf". When hercules has loaded the configuration and successfully started you can start issuing commands to the emulator.
