Amigo — Amiga Emulator vs Jammy

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.

Jammy is a free C# Amiga emulator for Windows and Linux that aims to run Workbench, games, and demos. It lists support for A1000, A500, A500+, A600, A1200, A2000, A3000, A4000, and CD32 models, with OCS, ECS, and AGA emulation. It emulates components including the Copper, Blitter, CIA, sprites, playfields, and audio. Supported floppy image formats for reading include ADF, zipped ADF, ADZ, DMS, and RP9; ATA hard disks support reading and writing. Development tools include a debugger, disassembler, automated code analysis, and SQLite storage for disassemblies. JavaScript and Lua APIs can run code on breakpoints, and a web API supports custom user interfaces. The releases page lists Windows Alpha and Linux Alpha release 0.0.30. The project reports DMA timing problems, incomplete cycle accuracy, poor emulation of CPUs above 7 MHz, and software that does not yet work. CD32 CD-ROM and NVRAM do not work, the IPF floppy reader is broken, and there is no ARM build. Linux lacks debugging interfaces, and its scripting, web, and database APIs need more work.
