Amiberry

Amiberry is a high-performance Amiga emulator for macOS (and ARM/Linux platforms) that brings Commodore's legendary home computers — from the A500 to the A4000 — back to life with accuracy, speed, and surprising polish.

What is Amiberry?

Amiberry is an open-source Amiga emulation engine optimised for modern hardware, descended from the venerable WinUAE lineage but rebuilt from the ground up for native ARM and x86-64 performance. It covers the full breadth of Commodore Amiga hardware — OCS, ECS, and AGA chipsets — and supports WHDLoad, the de-facto modern standard for running Amiga game and demo archives without the original floppy chaos.

Where vintage-computing emulators typically feel like archaeological dig sites — obtuse UIs, cryptic config files, dependency nightmares — Amiberry makes a genuine effort at approachability. The built-in setup wizard steps you through kickstart ROMs, memory sizing, and chipset selection without demanding that you already know what a Chip RAM ceiling is.

What does Amiberry do best?

Amiberry's strongest suit is WHDLoad integration: drop an archive into the configured games folder, and Amiberry's RetroArch-style scanner detects it, names it, and makes it launchable in two clicks — no more boot-disk rituals. This alone is the reason most people choose it over the older and less tidy FS-UAE.

• AGA accuracy: Amiga 1200 and CD32 software — including late-era demos and games that stress the AGA blitter — renders with the fidelity you'd expect from a WinUAE core.
• Input configurability: Gamepad, keyboard, and mouse mappings are per-game and saved automatically; CD32 gamepad emulation is first-class.
• Netplay and save states: Rewind and save states make the notoriously brutal Amiga game library approachable without the original hardware's lack of mercy.
• Shader support: CRT scanline shaders give Workbench and games the authentic phosphor look on a 4K display, complete with curvature options.

I've run everything from Cannon Fodder and Sensible Soccer to Protracker module files and late-era Amiga demos through Amiberry without a crash or configuration fight that lasted more than ten minutes.

Is Amiberry free?

Yes — Amiberry is completely free and open-source under the GPL licence. You download and run it at no cost. The one thing you must supply yourself is a legally obtained Amiga Kickstart ROM image; Amiberry does not include Commodore's proprietary firmware (though Cloanto's Amiga Forever package is the straightforward way to get legal ROMs if you don't own original hardware).

Who should use Amiberry?

Anyone with a nostalgia streak for the Amiga golden age of 1985–1994 — demoscene enthusiasts, retro game collectors, and anyone who grew up with a Miggy — will find Amiberry the most practical entry point on macOS. It also appeals to a narrower audience of developers building or testing Amiga software and musicians using OctaMED or Protracker trackers in their original native environment.

If you've never touched an Amiga before, Amiberry's setup wizard is gentle enough to orient a newcomer, but you'll benefit from spending twenty minutes with a quick-start guide before diving in. The Amiga's hardware model is genuinely unlike anything modern, and understanding chip memory versus fast memory, chipset generations, and the role of kickstart ROMs will spare you frustration.

What are the best Amiberry alternatives?

The main competitors depend on your priorities. FS-UAE is the other serious macOS-native Amiga emulator — it's based on the same WinUAE core, has a friendlier GUI in some respects, and benefits from the FS-UAE Launcher front-end. For purists who want maximum hardware accuracy and don't mind a Windows-centric workflow, WinUAE under Wine or a VM remains the gold standard — but it's overkill for casual use on a Mac. Outside the Amiga world, MAME covers a far broader range of retro platforms but treats the Amiga as one of thousands of targets rather than a first-class citizen, which shows in the configuration depth required.

My honest take: if you primarily want to play games and run WHDLoad titles with minimal ceremony, Amiberry beats FS-UAE on the Mac today. If you're doing deep hardware debugging or cycle-exact timing research, WinUAE in a VM is worth the overhead.

How actively is Amiberry maintained?

Amiberry is actively maintained with regular releases that track upstream WinUAE core improvements and respond quickly to macOS compatibility changes. The project has a healthy GitHub presence and a dedicated community. Apple Silicon Macs run Amiberry natively — no Rosetta translation required on recent builds — which means performance headroom is generous even for the most demanding AGA software.
