FS-UAE vs Jammy

FS-UAE is a free Amiga emulator for Linux, macOS, and Windows, with an emphasis on games and support for high-end Amiga systems. It emulates systems including the Amiga 500, 500+, 600, 1000, 1200, 4000, CD32, and CDTV. It accepts floppy images such as ADF and IPF, CD-ROM images such as ISO and BIN/CUE, and computer folders mounted as Amiga hard drives. Its optional graphical Launcher configures the emulator without configuration files and can identify games through the Open Amiga Game Database, retrieving covers and screenshots. The Launcher can also recognize many archived WHDLoad games. An on-screen menu supports gamepad control for tasks such as changing disks and loading save states. FS-UAE supports cross-platform online play and offers graphics options including aspect correction, zoom, shaders, and visual themes. It is free software under GPLv2, with some project parts and dependencies under other open-source licenses. It requires a moderately fast computer with accelerated OpenGL graphics; a gamepad or joystick is recommended, and users should ideally have the Kickstart ROMs for the systems they want to emulate.

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.
