Amigo — Amiga Emulator vs Copperline

Amigo is a free emulator for running classic Commodore Amiga software on iPhone, iPad, and Apple Silicon Mac. On its first launch it boots a built-in AROS ROM, but running genuine Amiga software requires the user’s own Kickstart ROM and disks. Configurations range from A500, A1200, A4000, and CD32 systems to 68060 workstations, with OCS/ECS/AGA chipsets and up to 256 MB of Zorro III RAM. It accepts floppy, hard-drive, and CD images in formats including ADF, HDF, ISO, and CHD. Input options include touch, keyboards, pointing devices, Bluetooth and USB controllers, and Apple Pencil features. Amigo has save states, autosave, named configurations, and iCloud sync for configurations and save states. It requires iOS or iPadOS 17 or later, or an Apple Silicon Mac with macOS 14 or later. The project is GPL-2. Its privacy policy says the app collects no data, makes no internet connections itself, and does not upload user files.

Copperline is a free, open-source Amiga emulator for games, demos, and development, available on Linux, macOS, Windows, and in browsers. It models OCS, ECS, and AGA machines with 68000 through 68060 CPUs, plus expansion boards, hard disks, and CD drives. Its Debug workspace puts registers, disassembly, and memory beside the Amiga display, and supports reverse stepping from snapshots. Development features include scripted inputs and captures, repeatable test sessions, headless runs, a JSON-RPC control protocol, and debugging Amiga source code from Visual Studio Code. Rollback netplay supports two players on desktop or in browsers, up to four desktop players with the four-player adapter, and up to eight spectators. A libretro core supports RetroArch, including A500, A1200, and CD32 software, WHDLoad, playlists, save states, four local controller ports, and RetroArch netplay. Copperline includes the AROS Kickstart replacement, though some software needs an original Kickstart ROM. It does not support high-density Amiga floppy images or sector-based PC/CrossDOS images.
