Amiberry vs Jammy

Amiberry is a free Amiga emulator built on the WinUAE core. It runs on Android, Linux, macOS, and Windows, and supports Amiga models including the A500, A1200, A4000, CD32, and CDTV, as well as listed arcade systems. It supports save states, hardware acceleration, and a wide range of disk image formats, including ADF, HDF, ISO, and CHD. Kickstart is not included. The emulator can launch WHDLoad titles with automatic configuration and offers CRT bezels, built-in shaders, and external GLSL shaders. Its interface can be navigated by mouse or gamepad, and floppy images, hard files, and configuration files can be dragged into it. A custom JIT compiler supports ARM64 and x86-64. The built-in update checker verifies downloads with SHA256. Amiberry is licensed under GPLv3, and the site lists packages or installation options for its supported platforms. The project welcomes bug reports, feature suggestions, and pull requests.

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.
