In their own words
Jammy
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.
UAE4ALL2 Mod
UAE4ALL2 Mod is an Amiga emulator for PlayStation Vita and Nintendo Switch, with support for Amiga 500 and Amiga 1200 systems. It reads ADF, ADZ, HDF, and ZIP disk images, with ZIP available only for reading. The project says most Amiga games run at full speed with zero frameskip. Controls include six mappable sets, analog mouse control, and a virtual keyboard whose position and transparency can be adjusted. The emulator can mount up to four HDF files at once; maximum file sizes are below 2 GB on Vita and below 4 GB on Switch. Savestates support HDF, import and export, thumbnail previews, and an automatic slot. It also supports shaders, with automatic full 1080p in Switch docked mode. Multiplayer supports up to four paired controllers on Vita TV and up to eight on Switch. Users must provide Amiga Kickstart ROM files; the installation instructions specify kick13.rom and kick31.rom. Some games have known issues, including missing graphics in Banshee AGA and unsupported cycle-exact emulation needed for Nebulus 2. UAE4ALL2 Mod is free and GPL-2.0 licensed.
