## Project history and usage

Afterglow is a macOS emulator and screen-saver host for classic After Dark modules. It is designed to preserve and run original 68k module code on current Macs.

### Project history

Afterglow was created as a non-commercial software-preservation project to run classic After Dark screen savers on modern macOS. Rather than remake the animations, it uses the Musashi 68k CPU emulator and reimplements enough Macintosh Toolbox and operating-system APIs to execute original modules.

### Adoption history

Afterglow targets modern macOS 15 or later on both Apple silicon and Intel. It can import modules from original files and archives or install preserved software releases through its built-in Internet Archive browser.

### How it is used

Users import After Dark modules by dragging module files, disk images, directories, or supported archives into Afterglow; the app can also browse preserved releases from the Internet Archive.

Afterglow installs a modern macOS screen-saver component and keeps imported modules and related application data under ~/Library/Application Support/Afterglow. The official help describes this as application data, not a configuration file, so config-file-location remains null.

### Why package nerds care

Afterglow is a preservation-oriented compatibility package: it runs original Motorola 68k After Dark module code without requiring a classic Macintosh ROM or operating-system installation. Its specialized emulator preserves a distinctive body of 1990s desktop software in a modern package.

### Timeline

- 2026: Afterglow's initial public release supports macOS 15+, Intel and Apple silicon, module importing, and modern macOS screen-saver integration.

### Related projects
