Our verdict on Jammy

Jammy is an open-source Amiga emulator written in C#, aimed at developers and technically inclined users who need more than basic game playback. It covers Amiga models from the A1000 through the A4000, along with the CD32, and supports the OCS, ECS, and AGA chipsets. Its stated scope includes Workbench, games, and demos, making it relevant for software preservation, compatibility work, and emulator-driven development across classic Amiga configurations.

Its strongest distinction is the depth of its developer-facing feature set. Jammy includes a debugger and disassembler, plus JavaScript and Lua APIs for programmatic control. A web API supports custom user interfaces, which gives developers a foundation for building specialized tooling around the emulator. The storage and expansion coverage is also broad: it reads ADF, zipped ADF, ADZ, DMS, and RP9 floppy images; supports ATA hard disks with read/write capability; and models Chip, trapdoor, CPU-slot, and Zorro II/III RAM expansions. Audio emulation and output round out the core environment.

Jammy’s platform fit is focused rather than wide, with official packaged releases for Windows and Linux. The project is identified as an alpha release and documents several limitations, so it suits users comfortable with an evolving emulator and developer-oriented workflows more than those seeking a finished consumer package. Users who need model coverage, disk and memory configuration, debugging, or scripting APIs should shortlist Jammy. Those prioritizing save states, netplay, bundled Kickstart ROMs, GPU rendering, or a broader host-platform range should choose an alternative.
