Z64K – Atari 2600, Commodore 64, Commodore 128, and VIC 20 emulator

Z64K is a pixel exact emulator of the Atari 2600, Commodore 64, Commodore 128, and VIC 20.

Keyboard mapping is positional to match real c64/c128/vic 20 key positions and combinations so some keys will not match PC keyboard keys.

The emulator is written in the Java programming language. You’ll need a current Java runtime environment.

Note this emulator is not released under an open source license.
