Meta Amiga Emulator

Meta Amiga Emulator is a free, open-source project aiming to bring cycle-accurate Amiga emulation to macOS, Linux, and Windows. It is best suited to developers and Amiga enthusiasts following emulator development; its broad design is compelling, but it cannot run Amiga software yet.

Overview

The project is designed for games, Workbench, and demoscene productions across Amiga models from the A1000 through A4000, plus CDTV and CD32, with OCS, ECS, and AGA chipset support as a goal. That range gives the project a clear purpose, but it remains a target rather than usable compatibility: the current pre-alpha work covers the specification, architecture, build, and CI, and produces no runnable emulator.

Meta is a clean-room implementation written from scratch in C++23 and licensed under GPL-3.0-or-later. Its freestanding core is planned around explicit video, audio, input, storage, and clock interfaces, a structure that should help keep the emulation core portable. The identical-source builds and determinism goals are technically ambitious; for players, they matter only once there is an emulator to use.

Key features

• Broad planned media support: The specification spans ADF, Extended ADF, ADZ, DMS, SCP flux, KryoFlux raw, IPF/CAPS, HDF, directory-mapped volumes, LHA/WHDLoad, and ISO/CUE/CHD. This would suit collectors with varied disk and CD images if implemented. The breadth is useful as a roadmap, not a reason to switch from a working emulator today.
• User-owned ROM handling: Kickstart ROMs are not included. The project says it supports ROMs users own, including encrypted Amiga Forever files unlocked with the user's rom.key, and bundles AROS as a redistributable fallback. That gives the plan a route for users with their own ROMs while avoiding a bundled copyrighted Kickstart, but it does not remove the need for a runnable build.
• Accuracy and repeatability goals: The project targets at least 99% run-to-playable game compatibility, booting every shipped ROM revision to usable Workbench, and at least 99% frame-exact demoscene results. Its planned verifier compares framebuffer and audio hashes for a deterministic corpus, with regressions intended to fail CI. These are measurable quality goals, though they remain targets rather than demonstrated compatibility.
• Cross-platform engineering: The design requires identical inputs to produce bit-identical runs across platforms and build configurations. CI is described as using warnings-as-errors and ASan, UBSan, and TSan across three platforms and two architectures. This is a strong foundation for catching implementation defects, but the present build still does not produce software that users can run.
• Build and dependency constraints: Building the current core requires CMake 3.28 or newer, Ninja, and a supported C++23 compiler, so even developers need a modern toolchain. IPF/CAPS support is optional, requires the non-free capsimage library, and is specified to stay out of release binaries.

Pricing

Meta has one plan: Free / open source costs nothing, under GPL-3.0-or-later. There is no paid tier or trial to weigh against it. The meaningful limit is its status: the project is pre-alpha and has no emulator to run, so the free plan currently gives developers access to the project rather than players a usable Amiga environment.

Platforms

The stated host platforms are Linux, macOS, and Windows, built from identical sources. That is a useful cross-platform aim for people developing or tracking the project, but platform coverage does not yet translate into a working emulator on any of the three.

Who it's for

Meta is a reasonable project to follow if you care about clean-room emulator design, deterministic testing, or the challenge of supporting a wide range of Amiga hardware. Developers can inspect and build the current core with the required toolchain. Players who want to run games, Workbench, or demos should choose an existing emulator instead; Meta's roadmap puts the GUI, configuration, savestates, RTG, and releases in phase 8, whose exit criterion is release 26.1.0.

Pros and cons

• Pro: The planned machine range, media formats, and ROM approach cover varied Amiga setups, including user-owned encrypted Amiga Forever ROMs.
• Pro: A clean-room C++23 implementation, explicit core interfaces, deterministic-run requirement, and sanitizer-enabled CI give the project a concrete engineering direction.
• Con: There is no runnable emulator, so players cannot use it for Amiga software today.
• Con: The GUI, configuration, savestates, RTG, and releases are still placed in a later roadmap phase.
• Con: Building the current core requires a recent CMake version, Ninja, and a supported C++23 compiler, which adds setup work for developers without delivering a playable emulator.

Alternatives

FS-UAE is a free, open-source Amiga emulator for Linux, macOS, and Windows, making it the closer fit for someone who wants an existing desktop option. Amiberry is also free and open source under GPLv3, with Android support alongside Linux, macOS, and Windows, so consider it if Android matters. Damisoft Amiga Emulator is free and can start in a browser, but requires a Kickstart ROM and at least one disk. Amigo — Amiga Emulator is free on iOS and macOS, has no ads or accounts, and requires users to bring their own Kickstart ROM and disks. E-UAE is free, open-source software under the GPL. UAE4ALL2 Mod is a free option for Android and iOS. Jammy is free software under the MIT License for Linux and Windows. Buddi is budgeting software, not an Amiga emulator.

Verdict

Follow Meta if you want to track an open-source, cross-platform effort with unusually broad hardware, media, and accuracy goals. Its clean-room design is the strongest reason to watch it; the lack of a runnable emulator is the decisive reason to choose another option if you want to use Amiga software now.
