Summary

Copperline is a free, open-source Amiga emulator for games, demos, and development. It models OCS, ECS, and AGA machines using processors from the 68000 through 68060, with support for expansion boards, hard disks, and CD drives. A Debug workspace shows registers, disassembly, and memory alongside the Amiga display, and can reverse-step through snapshots. Development features include scripted inputs and captures, repeatable test sessions, headless runs, JSON-RPC control, and debugging Amiga source code from Visual Studio Code. Rollback netplay accommodates two players on desktop or in browsers; a four-player adapter enables up to four desktop players, with up to eight spectators. The libretro core works with RetroArch and supports A500, A1200, and CD32 software, WHDLoad, playlists, save states, four local controller ports, and RetroArch netplay. Copperline runs on Linux, macOS, Windows, and in browsers. It includes the AROS Kickstart replacement, but some software requires an original Kickstart ROM. High-density Amiga floppy images and sector-based PC/CrossDOS images are not supported.

Who it is for

Copperline suits people who want to run Amiga games or demos, or work on Amiga software and repeatable tests. RetroArch users can also use its libretro core for supported Amiga software.
