Install Vice on Linux
Vice is an emulator for the 8 bit line of Commodore computers (VIC-20 , Commodore 64, etc.)
Vice is available in most repositories, however, they often do not include the ROMs required to run it. so, the process is not as straightforward as it might seem.
This video makes it more straightforward and does most of the work from the GUI (KDE in this case) with only a single command from the command line.
