Clock Signal (CLK) is a low-latency emulator of many classic 8-bit and 16-bit home computers and consoles, including the ZX Spectrum, Apple II, Atari ST, Amstrad CPC, and MSX. It emphasizes single-click loading of software and accurate signal-level reproduction of original video and audio outputs.
Use cases
- emulate zx spectrum games from rom files
- run apple ii disk images with one click
- play atari 2600 cartridges on my mac
- accurately reproduce composite video output of a vic-20
- load cpc tapes without typing loading commands
- emulate msx software on linux
- run bbc micro software with minimal input latency
When to choose
- you want to launch classic software as easily as a native app, with no emulator setup
- you care about accurate video/audio signal reproduction and low latency
- you use macOS and want a native Metal-based retro emulator
- you need broad multi-machine emulation in a single program
When to avoid
- you need emulation of consoles or machines not on the supported list
- you want extensive emulator configuration, save states, or netplay features
- you need a highly polished emulation of the Archimedes, Amiga, or early PCs, which are less complete
- you prefer a plugin-based or multi-core emulator ecosystem like RetroArch
