Frodo is a portable Commodore 64 emulator that runs on a variety of platforms, with a focus on the exact reproduction of special graphical effects possible on the C64. It was also the world’s first Commodore 64 emulator without a “64” in its name. ;-)

Frodo comes in two flavors: The regular “Frodo” which uses a cycle-exact emulation, and the simplified “Frodo Lite” which is less compatible but runs better on slower machines.
