CCS64
What CCS64 is
CCS64 emulates a Commodore 64 on a PC so users can run much of the original system's software. It models the console and peripherals such as the keyboard, joysticks, paddles, mouse, up to four 1541 disk drives, a cassette recorder, and many cartridges. Listed media formats include PRG, P00, T64, TAP, D64, G41, and G64. The documentation describes cycle-exact CPU emulation and pixel-exact VIC-II emulation, while SID filter and amplifier emulation is approximated. Users can record video with audio to AVI or audio to WAV files, and use a machine-code monitor, backward tracing, and replay of up to 60 minutes of emulation history. Internet multiplayer for T64, D64, and PRG files uses the Kaillera client. The maker calls CCS64 shareware that is free to use and copy, while asking regular users to register; registration is listed at $30, paid once. The current download page lists 32-bit and 64-bit Windows executables, and supported platforms also include DOS, Linux, and Unix.
