Summary
Frodo is a portable Commodore 64 emulator for Linux, macOS, and Windows. It focuses on recreating the C64’s special graphical effects and supports disk and tape software, game cartridges, and formats including D64, G64, T64, TAP, X64, and LYNX. It has a cycle-exact regular mode and Frodo Lite, a less compatible version intended to run better on slower machines. Version 4.5 adds Datasette TAP emulation, support for several banked cartridge types, and command-line auto-start for disk and tape images, cartridges, and C64 BASIC program files. TAP emulation is not available in Frodo Lite. Frodo can detect connected controllers for C64 joystick ports and map other controller buttons to C64 keys. Display settings include windowed or fullscreen mode and initial window size. The official site lists version 4.5 and notes that its changed snapshot format cannot read snapshots made with earlier versions. Frodo is free and listed under the GPL-2.0 license.
Who it is for
Frodo suits people who want to run Commodore 64 software on Linux, macOS, or Windows, including users on slower machines who may prefer Frodo Lite. Its controller mapping and support for disk, tape, and cartridge formats also suit people using varied C64 media.
