What joy the good old Commodore 64 (CBM C=64) brings when it’s on my laptop’s
desk. I downloaded and installed the VICE emulator. It can do a lot things,
but of main interest are loading (playing) .d64 and .t64 images. These are
binary representations of disks and tapes, respectively. So in plain English
you can download the good old games and play them on your PC.

You can also install a SIDPLAY, which lets you play Commodore tunes!

stuff.
